Front

What is carrying capacity?

Back

The maximum number of individuals of a species that an environment can support sustainably.

Front

What happens to a population that exceeds its carrying capacity?

Back

The population starts to die off due to limited resources.

Front

What is the photic zone in the ocean?

Back

The upper layer of the ocean where sunlight penetrates, allowing photosynthesis to occur.

Front

Why are there fewer top predators in an ecosystem?

Back

There is not enough energy remaining in the ecosystem to support a large number of top predators.

Front

What does it mean for an enzyme to denature?

Back

Denaturation is the process where an enzyme loses its shape due to changes in pH or temperature, affecting its function.

Front

What is the significance of water's high heat capacity?

Back

Water's high heat capacity allows it to absorb and retain heat, stabilizing temperatures in large bodies of water.

Front

What is an ecosystem?

Back

A community of living organisms interacting with their physical environment.

Front

What role do producers play in an ecosystem?

Back

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

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are living components of an ecosystem, while abiotic factors are non-living physical and chemical elements.

Front

What is the role of decomposers in an ecosystem?

Back

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