Energy Flow

Front

What is energy flow in an ecosystem?

Back

Energy flow refers to the transfer of energy from one organism to another through food chains and food webs, starting from primary producers to various levels of consumers.

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another, starting with a primary producer and ending with a top predator.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, illustrating how different organisms are related through feeding relationships.

Front

What are primary producers?

Back

Primary producers are organisms, such as plants and algae, that can make their own food through photosynthesis, forming the base of the food chain.

Front

What are consumers?

Back

Consumers are organisms that cannot produce their own food and rely on consuming other organisms for energy. They are classified into primary, secondary, tertiary, and quaternary consumers.

Front

What is a trophic level?

Back

A trophic level is a specific position in a food chain or food web, representing the flow of energy from one level to the next.

Front

What is an apex predator?

Back

An apex predator is a top predator in a food chain that has no natural enemies and plays a crucial role in maintaining the balance of the ecosystem.

Front

What is an autotroph?

Back

An autotroph is an organism that can produce its own food from inorganic substances, typically through photosynthesis or chemosynthesis.

Front

What is a heterotroph?

Back

A heterotroph is an organism that cannot produce its own food and must consume other organisms for energy.

Front

What is an invasive species?

Back

An invasive species is a non-native organism that, when introduced to a new ecosystem, disrupts the local environment and can outcompete native species.
