Unit 5: Ecology and Environmental Science Test Review

Front

What is Ecology?

Back

Ecology is the branch of biology that studies the interactions between organisms and their environment, including the relationships among different organisms and their physical surroundings.

Front

Define Population in ecology.

Back

A population is a group of individuals of the same species that live in the same area at the same time.

Front

What are Producers in an ecosystem?

Back

Producers are organisms, typically plants and algae, that can make their own food through photosynthesis, forming the base of the food chain.

Front

What role do Consumers play in an ecosystem?

Back

Consumers are organisms that cannot produce their own food and rely on eating other organisms (plants or animals) for energy.

Front

What are Decomposers?

Back

Decomposers are organisms, such as bacteria and fungi, that break down dead organic material, returning nutrients to the soil.

Front

Explain the concept of Mutualism.

Back

Mutualism is a type of symbiotic relationship where both species benefit from the interaction, such as bees pollinating flowers.

Front

What is the significance of Biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, and it is crucial for ecosystem resilience and stability.

Front

How does deforestation impact carbon dioxide levels?

Back

Deforestation increases carbon dioxide levels in the atmosphere because fewer trees are available to absorb CO2 during photosynthesis.

Front

What is an Invasive Species?

Back

An invasive species is a non-native species that spreads widely in a new habitat, often causing harm to native species and ecosystems.

Front

Describe the Water Cycle.

Back

The water cycle is the continuous movement of water through evaporation, condensation, precipitation, and collection in bodies of water.
