Unit 5 - 7th OL Review Ecology, Photosynthesis, Energy transform

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular ecosystem, including the number of different species and their interactions. A more diverse ecosystem is generally more sustainable.

Front

What type of energy is produced during photosynthesis?

Back

Chemical energy is produced during photosynthesis, as plants convert sunlight into energy stored in glucose.

Front

What do the arrows in a food chain indicate?

Back

The arrows in a food chain represent the flow of energy from one organism to another.

Front

What is the role of algae in an energy pyramid?

Back

Algae are typically at the bottom of the energy pyramid, serving as primary producers that convert sunlight into energy.

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as chemical energy to kinetic energy.

Front

What is the significance of producers in an ecosystem?

Back

Producers, like plants and algae, are essential for ecosystems as they create energy through photosynthesis, supporting all other organisms.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem, showing how energy flows through different species.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position or state.

Front

How do plants use chemical energy?

Back

Plants use chemical energy to perform various functions, including growth, nutrient transport, and cellular respiration.
