Why are some biomes more productive than others?

What factors cause some ecosystems or biomes to be more productive than others? Tropical rainforests have a high productivity rate because warm temperatures are suitable for photosynthesis, resulting in high global productivity. Open oceans: moderate production rates, but high global productivity. We rely on ecosystems to provide products and services. Some of the most important products and services provided by terrestrial ecosystems include water storage, regulation of temperature, and soil formation. Some of the most important products and services provided by marine ecosystems include seafood consumption and carbon dioxide removal from the atmosphere. Biomes can be divided up into three main types: grasslands, forests, and deserts.

Some biomes are better suited for certain uses than others. Deserts are poorly suited for human development because they lack sufficient water and fertile land is needed to support population centers. As a result, desert areas are used primarily for wildlife conservation and provide resources such as minerals and fuel. Forests have the potential to supply many valuable products and services but often do not due to deforestation. Ancient forest ecosystems can remain intact for thousands of years but new growth is limited by low temperatures that kill growing tips and prevent new shoots from developing. This is why ancient forests tend to contain fewer species than tropical forests - since new organisms cannot invade them. Productivity varies between biomes because it depends on the type of organism that exists there. For example, coral reefs are highly productive because they contain large numbers of small fish which are efficient at converting light energy into food.

What makes a productive biome?

The most productive ecosystems have high temperatures, a lot of water, and a lot of accessible soil nitrogen. Nitrogen is the key ingredient for making new plants grow quickly. The more available nitrogen there is in an ecosystem, the more plants will be able to use it up through their growth processes.

Ecosystems that lack nitrogen can still produce food, but only certain types of plants will do so. Woody plants need nitrogen to make their fibers and chemicals. Food crops like corn and soybeans need nitrogen to make more copies of themselves. That's why farmers often apply nitrogen fertilizer to their fields. The nitrogen from the fertilizer gets absorbed by the plants and becomes part of their bodies, ready to be used for building healthy seeds or growing bigger leaves if they're a corn plant or tree, respectively.

Tree species vary widely in how much energy they consume as adults. Some trees rely on sunlight alone for photosynthesis, while others also use oxygen during this process. The more carbon dioxide trees absorb using oxygen instead, the more oxygen there will be in the atmosphere later when they release their stored carbon back into it.

Why is productivity important in an ecosystem?

Each trophic level in an ecosystem has its own quantity of biomass. Primary producer productivity is very essential in any ecosystem since these species provide energy to other living creatures through photoautotrophy or chemoautotrophy. Secondary consumers consume most of the prey that primary producers produce, and so on. At the top of the food chain are predators which eat other animals; they do not eat plants. They may have special organs such as claws, teeth, and feathers that help them catch their prey. Predators control the number of individuals at each level by dying or getting eaten themselves. This is called predator-prey balance.

Productivity is important because it allows organisms to use energy from the environment effectively. If all organisms were equally efficient producers, then the least efficient ones would be outcompeted by more efficient competitors. Therefore, evolution has made organisms vary in how efficiently they convert energy into tissue and structure. Productivity also affects an organism's ability to survive by allowing them to spend energy on activities other than reproduction (i.e., growth, defense, activity).

An increase in productivity can result from either a decrease in one's efficiency as a producer or an increase in one's amount of output per unit time. For example, if a carnivorous plant produced more flowers or fruits than normal plants of its type, then it would have higher productivity.

What do the most productive ecosystems have?

Fertile estuaries and marshes, coral reefs, terrestrial plants on wet alluvial deposits, and intensive agriculture are the most productive ecosystems, with productivity rates of 10–25 x 103 kcal/m2/yr. Oceanic islands produce up to 100 x 103 kcal/m2/yr. Deserts are not very productive, with rate estimates ranging from less than 1 to 10 x 103 kcal/m2/yr.

Ecosystems work together as a system to provide food for their members. Ecosystems consist of organisms living in an environment that contains water or soil. An ecosystem is called a "community" if it includes many different species of organisms. Ecosystems are important because they provide habitats for many different types of organisms, which would otherwise be exposed directly to the elements. They also provide nutrients for their inhabitants which would not be available otherwise. Finally, they can be considered a source of energy, since some organisms collect solar radiation and transform it into chemical energy used by other organisms.

Which ecosystem is considered the most productive?

Terrestrial ecosystems are usually more productive than aquatic ones, but both are limited by their availability of water. Forests are known to be the most productive ecosystem on Earth, with average annual rates of production between 1,843 and 2,685 kilocalories per square meter.

Which biome has the highest net productivity?

Forests in the tropics Tropical forests are the most diverse and productive terrestrial biomes in terms of biodiversity and primary output. The net primary production can reach 2–3 kg m2 y-1. This is more than twice the production of other biomes such as tundra or desert. The high productivity of tropical forests is due to a combination of factors, including greater sunlight exposure that allows for higher rates of photosynthesis, and water availability that promotes growth of oxygen-producing plants like angiosperms.

The main cause of death for tropical forest organisms is also one of the main causes of life for tropical forest organisms: disease. Infectious diseases are responsible for the death of about 250 species-years-1 in tropical forests. However, most of these deaths are due to infection by one single species: HIV/AIDS kills about 25 species-years-1. Non-infectious diseases account for almost all other species deaths (99%). Non-infectious diseases include injuries from falling trees, being run over by vehicles, or being preyed upon by predators. In addition, tropical forests are frequently cleared for farmland, which can lead to extinction if the habitat is not restored afterward. However, since this is usually done to raise crops for food rather than livestock, it isn't considered a problem for land management.
