Science STAAR Review

What role do scavengers play in the ecosystem?

• They are predators that hunt live animals.

• They consume dead plants and animals, helping to recycle nutrients back into the ecosystem.

• They compete with herbivores for food resources.

• They are primary producers that create energy from sunlight.

How do the shapes of leaves help plants survive?

• Broad leaves can float on water, helping plants survive in aquatic environments.

• All leaves are the same shape, which is best for all plants.

• Slim leaves are only found in desert plants to increase water absorption.

• Leaf shapes have no impact on a plant's ability to survive.

What are fossil fuels?

• Natural substances formed from the remains of dead plants and animals used as energy sources like coal, oil, and natural gas.

• Renewable energy sources derived from sunlight and wind.

• Minerals extracted from the earth's crust for construction purposes.

• Synthetic materials created in laboratories for industrial use.

What is photosynthesis?

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

• Photosynthesis is the method by which animals convert food into energy.

• Photosynthesis is the way plants absorb nutrients from the soil.

• Photosynthesis is the process of respiration in plants.

What is evaporation?

• The process of liquid water turning into water vapor due to heat.

• The process of water vapor turning into liquid water due to cooling.

• The process of water being absorbed by soil and plants.

• The process of water being filtered through a membrane.

What is the water cycle?

• The process of water moving through the atmosphere, including evaporation, condensation, and precipitation.

• A method of purifying water using chemical treatments.

• The cycle of water being stored in underground reservoirs only.

• The process of water being used in industrial manufacturing.

What is a cumulonimbus cloud?

• A type of cloud that is flat and spread out

• A tall, dense cloud associated with thunderstorms, capable of producing heavy rain, lightning, and tornadoes.

• A cloud that forms at high altitudes and is always white

• A low-lying cloud that brings fog and mist

What adaptations do aquatic plants have for survival?

• Floating leaves that allow them to absorb sunlight for photosynthesis.

• Deep roots that anchor them to the ocean floor.

• Thick stems to withstand strong currents.

• Brightly colored flowers to attract pollinators.

How does the sun interact with the ocean to form clouds?

• The sun cools the ocean, causing water to freeze into ice.

• The sun heats the ocean, causing water to evaporate, which then rises and cools to form clouds.

• The sun reflects off the ocean, creating a mirage that looks like clouds.

• The sun causes the ocean to churn, mixing cold and warm water to create clouds.

What is an underground aquifer?

• A type of surface water body

• A layer of water-bearing rock that can store and transmit groundwater.

• A man-made reservoir for storing water

• A geological formation that prevents water flow
