Back

Energy is transferred from primary producers to consumers, in one direction only.

Front

What type of diet do leopard seals have?

Back

Leopard seals are carnivorous.

Front

What happens to disease spread when a population nears its carrying capacity?

Back

Disease spread is likely to increase due to limited resources.

Front

What type of reaction occurs when energy is used to attach a phosphate group to ADP, forming ATP?

Back

This is an endothermic reaction.

Front

What is a synonym for producer in an ecological context?

Back

Autotroph is a synonym for producer.

Back

An autotroph is an organism that produces its own food, typically through photosynthesis.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.

Front

Explain the concept of carrying capacity.

Back

Carrying capacity is the maximum population size that an environment can sustain indefinitely.

Front

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

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass, while a food web is a complex network of interconnected food chains.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.
