Semester 1 Final Review

Front

What are limiting factors in an ecosystem?

Back

Limiting factors are resources such as food, water, sunlight, shelter, and space that restrict the growth and population of organisms in an ecosystem.

Front

What is an abiotic factor?

Back

Abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems, such as water, sunlight, and temperature.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a particular species that an environment can support sustainably without degrading the habitat.

Front

How does deforestation affect the carbon cycle?

Back

Deforestation reduces the number of trees that can absorb carbon dioxide, leading to an increase in greenhouse gases in the atmosphere and contributing to climate change.

Front

What are some effects of climate change?

Back

Effects of climate change include droughts, flooding, melting of polar ice caps, and increased frequency of extreme weather events.

Front

Define ecosystem.

Back

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

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are living components of an ecosystem (e.g., plants, animals), while abiotic factors are non-living components (e.g., water, sunlight, soil).

Front

What role do producers play in an ecosystem?

Back

Producers, such as plants and algae, convert sunlight into energy through photosynthesis, forming the base of the food chain.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, keeping the planet warm enough to support life.

Front

What is biodiversity?

Back

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