It is essential in both natural and manmade ecosystems. It is concerned with nature's diversity, the biosphere. It refers to differences between plant, animal, and microbial species. Biological diversity contributes to the stability and resilience of ecosystems by preventing their inhabitants from going extinct too quickly or removing important functions they may have performed for millions of years.
In science, technology, and society, biological diversity is defined as "the variety of life on earth, as evidenced by the number of distinct organisms within each species, and the distribution of those organisms across geologic time and space."
Biological diversity affects many people in many ways, either directly or indirectly. Humans benefit from the services that living organisms provide, such as food, clean air, water, climate regulation, soil formation, disease prevention, and aesthetic beauty. In addition, there are other benefits that come about because different organisms interact with one another, such as the evolution of new species due to natural selection or the introduction of new genes into populations through pollen migration or hybridization.
Biological diversity is important because it helps to maintain global ecological balance and sustainability. Without this diversity, certain areas of the world would be unable to support life as we know it today. Additionally, biological diversity provides humanity with a wealth of knowledge about how to prevent extinction and use resources more efficiently.
It refers to the diversity of living things on Earth, the ecosystems they form in connection to one another, and the genetic health of each species. It may also refer to the responsibilities that creatures play in their ecosystem's complicated interplay. To access this solution, you must first become a member of Study.com.

Living organisms vary in many different ways. Their variety includes differences in shape, size, structure, composition, complexity, and behavior. This variety provides scientists with a wide selection of subjects upon which to base studies of biodiversity. For example, biologists study plants because there are so many types of them: grasses, trees, shrubs, wild flowers, and crops all belong to the plant kingdom. They also study animals because there are so many kinds of them: fish, birds, insects, and mammals.
Biodiversity is important because it tells us about the past and present state of life on earth. Living organisms have changed over time through evolution. The process by which new species develop is called diversification. And extinction is when species go away forever because they die out or are replaced by other species. Over time, these processes have caused major changes to occur many times in the history of life on earth. For example, dinosaurs once dominated the land but then were killed off by a massive asteroid impact.
Biodiversity, also known as biological diversity, refers to the variety of creatures that exist on Earth. Their interpersonal ties and their interactions with the environment are inextricably linked. It consists of a wide range of plants, animals, and microbes. Flora and Fauna: A flora region is made up of the plants present in a specific location. For example, the tropical rainforest flora includes all the plants found in a tropical rainforest. The species within this floristic community are very diverse because they have had many generations to evolve unique traits. Old growth forests contain many different species because old trees have time to mature and die which provides space for more young trees to grow. In contrast, tree plantations only contain one or two species because seedlings are harvested when they are grown large enough for timber production. Landforms: A fauna region is composed of the animals present in a specific location. For example, the jungle fauna includes all the animals found in the tropics. This would include mammals, birds, reptiles, amphibians. Biomes: A biome is a terrestrial ecosystem that is dominated by one plant group (for example, grasslands or forests) that can not be invaded by other species. Soils, climate, and topography play important roles in determining what types of ecosystems will develop where. Biomes may overlap geographically (for example, tropical forest and savanna), but they represent distinct ecological communities governed by different factors such as rainfall and temperature.
Biodiversity is also significant because certain creatures may coexist in a symbiotic relationship. In the rainforest, for example, plants rely on animals to disseminate their seeds, and diversity allows various animals to fulfill the same role for different plants. Pollinator diversity grows in lockstep with plant diversity. When one species goes extinct so do they all.
Biodiversity is critical to the survival of the rainforest because without these living things, the ecosystem would collapse. They help prevent erosion by breaking down rocks with their bodies, provide food for other organisms, and remove harmful chemicals from the soil. Without them, the rainforest would be destroyed over time due to its sensitive environment.
Biodiversity is important to humans too! Many people collect insects for entertainment or as a source of food. There are even organizations that seek to protect rare species by creating sanctuaries where they can live in peace.
In conclusion, the loss of biodiversity threatens the survival of the rainforest because it removes some of the key ingredients required for life. If the rainforest was to disappear, there would be no more insect pollinators, no more seed dispersers, and no more natural defenses against toxic chemicals.
The variety of living species within a particular region is referred to as biodiversity. Biodiversity can be measured by counting the numbers of individual organisms or their parts (e.g., eggs, pollen) that have been sampled from a defined area. Or it can be estimated by comparing the differences in species composition between two or more areas with different levels of diversity.
Biodiversity is important because it provides many benefits for humans. For example, new drugs are derived from natural products - which are molecules produced by plants, animals, and micro-organisms - and increasing biodiversity could lead to the discovery of more effective medications.
Biodiversity also has economic value. For example, pollinators such as bees help produce one third of our food supply. Without them, most plants would need multiple guards against insect attack, which would increase production costs.
Finally, biodiversity has cultural significance. Many people believe that viewing or interacting with some types of wildlife can give them special powers. For example, some Native Americans think that birds bring them good luck, while others believe that certain animals protect certain places. Regardless of whether this belief is true or not, seeing rare animals or habitats helps people appreciate how special our world already is.
There are several creatures that are significant in an ecosystem, such as a forest. The environment is dominated by trees, deer, plants, birds, squirrels, and insects. There are many more creatures in an ecosystem that are not as visible. These include bacteria, fungi, and other organisms that live on or inside other organisms.
Trees are important in an ecosystem because they provide food for other living things and help clean the air. They also produce oxygen which we need to breathe. Debris from trees such as needles and leaves drop into the water or land surrounding the tree. This is called "falling debris". Animals eat the trees' fruits and seeds. This spreads the seeds far and wide so more trees can grow where those before them died. Without animals to spread the seeds, most of these trees would be cut down and their pieces used for fuel or building materials. Seeds from broadleaf plants like trees and bushes fall to the ground to start new plants. Some seeds remain inside the fruit or pod of a plant and will be eaten by animals who break them open with their teeth. This spreads the seed farther away from the parent tree/bush than if it had fallen to the ground. Animals also play a role in destroying trees by chewing them with their teeth or digging up roots with their claws.
