What is the principle of reflection in relation to light and mirrors?

Back

The principle of reflection states that when light hits a smooth surface, such as a mirror, it bounces back at the same angle at which it hit the surface.

What factors affect the survival of organisms in a biome?

Back

Factors that affect survival include availability of food, water, shelter, climate, and interactions with other organisms, such as predators and competitors.

What type of energy powers a solar-powered calculator?

Back

A solar-powered calculator uses light energy, which is converted into electrical energy to power the device.

What is the role of a consumer in a food chain?

Back

A consumer is an organism that eats other organisms (producers or other consumers) for energy. In this context, the grasshopper is a consumer that eats producers like grass.

What happens to water when it absorbs solar energy?

Back

When water absorbs solar energy, it can change state from liquid to gas, a process known as evaporation.

Front

Define 'biome' in the context of ecosystems.

Back

A biome is a large geographic biotic unit, a major community of plants and animals with similar life forms and environmental conditions, such as a temperate forest or desert.

Front

What is the difference between producers and consumers in an ecosystem?

Back

Producers are organisms that create their own food through photosynthesis (like plants), while consumers are organisms that eat other organisms for energy.

Front

Explain the concept of energy transfer in a food chain.

Back

Energy transfer in a food chain occurs when one organism eats another, passing on energy from the producer to the consumer. Typically, only about 10% of the energy is transferred to the next level.

Front

What is the significance of light energy in the natural world?

Back

Light energy is crucial for photosynthesis, which allows plants to produce food and oxygen, forming the base of most food chains.

Front

How do environmental factors influence the characteristics of a biome?

Back

Environmental factors such as climate, soil type, and availability of water shape the types of plants and animals that can thrive in a biome.
