Biology PMA 2 Review 23/24

Front

Why are there so few aquatic plants and phytoplankton that live at the bottom zones in the ocean?

Back

Most sunlight is absorbed before reaching these levels. As a result, the bottom zone of the ocean has little to no light.

Front

What is cohesion in the context of water?

Back

Cohesion is the property of water that allows it to stick to itself, forming droplets.

Front

What role do mutations play in genetics?

Back

Mutations within a DNA sequence are natural processes that produce genetic diversity.

Front

What process uses sunlight to convert carbon dioxide and water into carbohydrates and oxygen?

Back

Photosynthesis.

Front

What is a consequence of an increase in greenhouse gases?

Back

Sea levels rising.

Front

What is photosynthesis?

Back

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

Front

Define aquatic plants.

Back

Aquatic plants are plants that have adapted to living in water environments, either partially or fully.

Front

What is the significance of decomposers in aquatic ecosystems?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.

Front

Explain the concept of limiting factors in an ecosystem.

Back

Limiting factors are environmental conditions that restrict the growth, abundance, or distribution of organisms.

Front

What is the difference between adhesion and cohesion?

Back

Adhesion is the attraction between different substances, while cohesion is the attraction between similar substances.
