Back

Tropical rainforest.

Front

What happens to the fox population if the wild rabbit population decreases?

Back

The fox population will likely decrease.

Front

Why is estimating commercial fish population sizes important?

Back

Both: Commercial fishing employs many people, and poor estimates could lead to job losses; commercial fish provides food for many people, and poor estimates could leave people without food.

Front

What type of population would you estimate using a quadrat?

Back

Plant populations or stationary organisms.

Front

Front

Define 'biome'.

Back

A biome is a large geographical biotic unit, a major community of plants and animals with similar life forms and environmental conditions.

Front

What is the role of producers in an ecosystem?

Back

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

Front

Explain the concept of carrying capacity.

Back

Carrying capacity is the maximum population size of a species that an environment can sustain indefinitely without degrading the environment.

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 ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, often following a disturbance.
