Nature and Environment Assessment

What is the process by which plants make their own food?

• Photosynthesis

• Digestion

• Transpiration

• Respiration

Name the pigment that helps in photosynthesis.

• anthocyanin

• chlorophyll

• xanthophyll

• carotene

What are the main ingredients needed for photosynthesis?

• Oxygen, glucose, and nitrogen

• Sunlight, carbon dioxide, and water

• Carbon monoxide, water, and soil

• Sunlight, oxygen, and minerals

Explain the term 'food chain'.

• A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

• A food chain is a complex web of interactions between multiple ecosystems.

• A food chain describes the habitat of a single species.

• A food chain is a circular pattern of energy flow among organisms.

What is the role of producers in a food chain?

• Producers are organisms that decompose organic matter.

• Producers are consumers that eat plants.

• Producers rely on other organisms for energy.

• Producers convert sunlight into energy and form the base of the food chain.

Identify a primary consumer in a food chain.

• Rabbit

• Eagle

• Frog

• Grass

What happens to energy as it moves up the food chain?

• Energy is completely transferred to the top predators.

• Energy increases as it moves up the food chain.

• Energy remains constant as it moves up the food chain.

• Energy decreases as it moves up the food chain.

Describe the water cycle in your own words.

• The water cycle is a one-time event that does not repeat.

• The water cycle is the process of water moving from the ground to the atmosphere and back, involving evaporation, condensation, precipitation, and collection.

• The water cycle only involves the movement of water in rivers and lakes.

• The water cycle is the process of water being stored underground indefinitely.

What are the stages of the water cycle?

• Sublimation, filtration, irrigation, evaporation

• Evaporation, condensation, precipitation, collection

• Precipitation, absorption, evaporation, filtration

• Condensation, filtration, evaporation, runoff

How does evaporation occur in the water cycle?

• Evaporation is the process where water is heated and changes from liquid to vapor, rising into the atmosphere.

• Evaporation is the process of water being absorbed by soil.

• Evaporation occurs when water freezes and turns into ice.

• Evaporation happens when vapor condenses back into liquid water.
