Front

What is a Food Web?

Back

A Food Web is a complex network of feeding relationships among various organisms in an ecosystem, showing how energy and nutrients flow through different trophic levels.

Front

What are abiotic factors?

Back

Abiotic factors are the non-living components of an environment, such as temperature, light, air, water, and soil.

Front

How much energy is available in herbivores if there is 1000 Kcal in producers?

Back

If there is 1000 Kcal available in the producers (trophic level 1), then 100 Kcal is available in the herbivores (trophic level 2).

Front

Which level has the most energy available in an ecosystem?

Back

The producer level has the most energy available in an ecosystem.

Front

What is a Tertiary Consumer?

Back

A Tertiary Consumer is an organism that eats secondary consumers and is at the top of the food chain.

Front

Define a Food Chain.

Back

A Food Chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Front

What are biotic factors?

Back

Biotic factors are the living components of an environment, including plants, animals, and microorganisms.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis, forming the base of the food chain.

Front

Explain the concept of trophic levels.

Back

Trophic levels are the hierarchical levels in an ecosystem, defined by how energy and nutrients are transferred from one organism to another.

Front

What is the difference between primary and secondary consumers?

Back

Primary consumers eat producers (plants), while secondary consumers eat primary consumers (herbivores).
