Biology Review

Front

What are producers in an ecosystem?

Back

Producers are organisms that can make their own food through photosynthesis, such as plants and algae. They form the base of the food pyramid.

What is the significance of genetic technology in biodiversity?

Back

Genetic technology can help restore extinct species and enhance biodiversity, but it requires careful assessment of costs, benefits, and risks.

Front

How can human activities impact species in an ecosystem?

Back

Human activities, such as pollution and habitat destruction, can have negative effects on species, leading to changes in behavior, health, and population dynamics.

Front

What is transpiration in plants?

Back

Transpiration is the process by which moisture is carried from plant roots to leaves, where it evaporates into the atmosphere, playing a crucial role in the water cycle.

Front

What are invasive species and their impact on ecosystems?

Back

Invasive species, like the hemlock wooly adelgid, can disrupt habitats and threaten native species by outcompeting them for resources.

Front

Define the term 'ecosystem'.

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic and abiotic components.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil, which supports plant growth and maintains ecosystem health.

Front

What is the food chain?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Front

Explain the concept of biodiversity.

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the diversity of species, genetic variation, and ecosystem diversity.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water within the Earth and atmosphere, involving processes like evaporation, condensation, precipitation, and transpiration.
