Food Chains and Food Webs

Front

What is a herbivore?

Back

An animal that primarily eats plants.

Front

What role does a tertiary consumer play in a food chain?

Back

A tertiary consumer is an organism that eats secondary consumers and is typically at the top of the food chain.

Front

Define a producer in an ecosystem.

Back

Producers are organisms that can make their own food, usually through photosynthesis, such as plants.

Front

What is a decomposer?

Back

Decomposers are organisms, like bacteria and fungi, that break down dead organic matter, returning nutrients to the soil.

Front

What is a primary consumer?

Back

A primary consumer is an organism that eats producers, typically herbivores like zooplankton.

Front

What is the difference between a food chain and a food web?

Back

A food chain is a linear sequence of organisms where each is eaten by the next, while a food web is a complex network of interconnected food chains.

Front

What is the significance of energy transfer in a food chain?

Back

Energy transfer in a food chain illustrates how energy moves from one trophic level to another, with energy decreasing at each level.

Front

What are trophic levels?

Back

Trophic levels are the hierarchical levels in an ecosystem, comprising producers, primary consumers, secondary consumers, and tertiary consumers.

Front

Give an example of a secondary consumer.

Back

A secondary consumer is an organism that eats primary consumers, such as a frog that eats zooplankton.

Front

What is the role of zooplankton in aquatic ecosystems?

Back

Zooplankton serve as primary consumers, feeding on phytoplankton and serving as food for larger animals.
