Ecology Summative Assignment

Front

What are producers in an ecosystem?

Back

Producers are organisms, like plants, that create their own food through photosynthesis and provide energy for other organisms.

Front

How has the human population changed from 1960 to 1990?

Back

The human population increased during this time.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What effect do fewer predators have on rabbit populations?

Back

Fewer predators can lead to an increase in the number of rabbits in an area.

Front

What human activity contributes to increased carbon dioxide levels?

Back

Burning fossil fuels contributes to increased carbon dioxide levels in the atmosphere.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is one of the key ingredients that plants use to produce glucose and oxygen during photosynthesis.

Front

What is the relationship between human population growth and carbon dioxide levels?

Back

As the human population grows, carbon dioxide levels tend to increase due to higher energy consumption and fossil fuel use.

Front

What is respiration in the context of ecology?

Back

Respiration is the process by which organisms convert glucose and oxygen into energy, releasing carbon dioxide and water as byproducts.

Front

What factors can limit the growth of a rabbit population?

Back

Factors such as limited food, lack of shelter, and presence of predators can limit rabbit population growth.

Front

What is the significance of plants in an ecosystem?

Back

Plants are crucial as they produce oxygen and serve as the base of the food chain by providing energy for consumers.
