Long Answer Questions
Explain why life on Earth depends on water.
Water is needed for photosynthesis and is a product of cellular respiration
Lamont has a dark container. He knows that the container has a mass of 2.0 g when it is empty. He cannot see inside the container. However, he is able to use a balance to determine that the container has a mass of 2.7 g. What can Lamont conclude about the container?
A. It contains matter.
B. It contains a solid.
C. It contains energy.
D. It contains a liquid.
A
Consumer who eats both plants and animals.
Omnivore
Describe how plants and animals get the water they need to survive.
Plants soak it in through their roots, animals consume it.
Explain how the cells of plants and goldfish release energy using cellular respiration.
They use oxygen to break down chemical bonds holding food molecules together. Energy is absorbed from the chemical bonds.
Why is the ability to move important to animals?
A. It helps them find food
B. It helps them stay warm
C. It helps them obtain oxygen
D. It helps them differentiate cells
A
What type of organism is an earthworm?
Decomposer
Decomposition is a physical and chemical process by which dead organic matter is broken down. Why is decomposition important to life processes?
It puts nutrients back into the ground for producers, gets rid of waste from other organisms
What is the difference between decomposers and consumers in a food web?
Decomposers can obtain energy by digesting chemical compounds that consumers cannot digest
What is the difference between cellular respiration and photosynthesis?
What is cellular respiration?
The process in which a cell takes oxygen to break down glucose in order to absorb energy from its chemical bonds
Why are people trying to find alternatives to fossil fuels?
It's a finite resource, pollution
Explain the role of photosynthesis in the cycling of matter between a plant and the human consuming it.
Photosynthesis supplies the glucose which is used as food molecules for the human consuming it.
Describe a primary consumer
You better get this right.
What is photosynthesis?
The process in which producers take sunlight, water, and carbon dioxide to produce glucose and oxygen.
Describe the path that carbon took to become a fossil fuel.
All life on Earth is carbon-based, and after organic matter died, it did not appropriately decompose under certain conditions, which over millions of years leads to the development of fossil fuels
Why are animals important to the process of photosynthesis?
Animals release carbon dioxide, which provides the starting materials for photosynthesis
Describe a tertiary consumer.
You better get this right.
Rule that states that every level of an energy pyramid contains only 10% of the level from before.
The 10% rule
Why do fossil fuels release carbon dioxide?
All organic matter comes from carbon, and fossil fuels are developed from organic matter over millions of years.
