Ecosystem Dynamics & Biodiversity Unit Test

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms (plants, animals, and microorganisms) interacting with their physical environment (soil, water, and climate).

Front

What is biodiversity?

Back

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

Front

Why are tropical rainforests important?

Back

Tropical rainforests are important because they provide habitat for a vast number of species, help regulate the Earth's climate, and produce oxygen.

Front

What is sustainable farming?

Back

Sustainable farming is an agricultural practice that focuses on producing food while maintaining the health of the environment, ensuring that resources are available for future generations.

Front

What is deforestation?

Back

Deforestation is the clearing or thinning of forests by humans, often to make way for agricultural activities, which can lead to habitat loss and decreased biodiversity.

Front

What factors affect population size in an ecosystem?

Back

Factors that affect population size include availability of food, space, water, and the level of competition among species.

Front

How do oil palm plantations impact orangutan populations?

Back

Oil palm plantations lead to habitat destruction for orangutans, reducing their living space and food sources, which can threaten their survival.

Front

What is the role of competition in ecosystems?

Back

Competition occurs when organisms vie for the same resources (like food, water, or space), which can influence population sizes and species distribution.

Front

What is habitat destruction?

Back

Habitat destruction is the process in which natural habitat is rendered unable to support the species present, often due to human activities like agriculture and urban development.

Front

What is a food chain?

Back

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