Study Notes

Fill in the blanks

Water evaporating from plant leaves returning to the atmosphere is called transpiration.
The water cycle is a continuous circulation between the soil, organisms, and air.
Runoff water flowing over Earth's surface is called runoff.
Food web models how energy is transferred in an ecosystem.
The source of all energy in a food chain is the sun.
A model of connected food chains is called a food web.
An organism that eats other organisms is a consumer.

Choose the correct answer

A model of how food chains are interconnected is called a food web.
All living organisms use energy and release gas as waste. Oxygen-carbon cycle explains the circulation of these gases.
The water cycle process where water vapor changes to a liquid is condensation.
Sunlight, carbon dioxide, and water are necessary for plants to produce their own energy

Additional Questions

Nitrogen is stored in the soil. Bacteria convert nitrogen to a form that plants can absorb. Animals obtain nitrogen by consuming plants.
Plants use sunlight, water, and carbon dioxide to produce food and release oxygen. In the oxygen-carbon cycle, animals take in oxygen and release carbon dioxide as waste.
Sunlight, carbon dioxide, and water are essential for plant production.
Producers, the first organisms in food chains, obtain energy directly from the sun.

Water Cycle

Evaporation: Water from the lake turns into water vapor.
Condensation: Water vapor turns into clouds.
Precipitation: Clouds release water as rain.
Runoff: Water flows back to the lake.
Water from the lake evaporates, causing the cycle to continue.

Food Chain

Arrows represent the flow of energy and nutrients.
The killer whale's energy source originates from the phytoplankton, ultimately the sun.
The predator in the example is the killer whale, and the first consumer is the zooplankton.
