Which term describes the variety of life in the world or in a particular habitat or ecosystem?

• Biodiversity

• Photosynthesis

• Succession

• Eutrophication

What is the process called when a community of organisms is replaced by another community over time?

• Evolution

• Ecological succession

• Photosynthesis

• Respiration

Match each human activity with its impact on biodiversity.

• Leads to loss of habitat and decreases biodiversity

• Deforestation

• Reduces waste and supports environmental health

• Composting

• Helps protect species and increases biodiversity

• Wildlife conservation

Which of the following is an example of a solution to reduce the impact of human activities on the environment?

• Planting native trees in urban areas

• Increasing fossil fuel consumption

• Expanding landfills

• Removing all predators from an ecosystem

A stable ecosystem is best described as (a)
