Why is trophic level important in an ecosystem?
If there is no producers (such as a plant), you cannot sea any primary consumers there. That is why trophic levels are important. They show availability of food/energy in a defined ecosystem, complexity of “who eats what”, dependency of any one to others, etc.
Which is the most essential in an ecosystem?
Decomposers. Decomposers are the most essential organism of an ecosystem because of their ability to recycle.
What is trophic level in an ecosystem?

Which 3 ecosystems have the highest productivity?
The world’s ecosystems vary tremendously in productivity, as illustrated in the following figures. In terms of NPP per unit area, the most productive systems are estuaries, swamps and marshes, tropical rain forests, and temperate rain forests (see Figure 4).
What is the most important factor in an ecosystems resilience?
Ecologists can deem heterogeneity and diversity as individual components. Further, redundancy and modularity are deemed to be important factors determining the resilience of an ecosystem.
What are the most important three factors in ecosystem?
Biotic components include plants, animals, decomposers. Nonliving components include air, water, land.
What is importance of food chain in ecosystem?
Food chains are important because they show the intricate relationships in ecosystems. It is seen that in food chains, each organism fills a specific niche in an ecosystem. Food chains reveal how each organism depends on someone else for survival.
Which organisms are the most important in a food web?
The primary producers are autotrophs and are most often photosynthetic organisms such as plants, algae, or cyanobacteria. The organisms that eat the primary producers are called primary consumers.
