What are renewable resources?

Back

Renewable resources are natural resources that can be replenished naturally over time. Examples include water, wind, sunlight, and plants.

Front

What part of the plant is responsible for making food from sunlight?

Back

The leaves of the plant are responsible for making food through the process of photosynthesis.

Front

What is the function of stomata in leaves?

Back

Stomata are small openings on the surface of leaves that allow for the exchange of gases, such as oxygen and carbon dioxide, between the leaf and the environment.

Front

What is habitat destruction?

Back

Habitat destruction is the process in which natural habitats are altered or destroyed, leading to a loss of biodiversity and the displacement of species.

Front

What is one major cause of deforestation?

Back

Urbanization is a major cause of deforestation, as it involves the conversion of forests into urban areas for housing and infrastructure.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (a type of sugar) and oxygen.

Front

What is 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 role of guard cells in plants?

Back

Guard cells are specialized cells that control the opening and closing of stomata, regulating gas exchange and water loss in plants.

Front

What is the impact of pollution on biodiversity?

Back

Pollution can harm ecosystems and reduce biodiversity by contaminating air, water, and soil, leading to the decline of species.
