Fruit and vegetable scraps can be put into compost bins. Water is also needed for composting to be effective. With frequent turning, the compost will turn into soil after about three months.
What is C-Decomposers break down the organic matter.

Michigan's Isle Royale is a small island in the northwestern part of Lake Superior which is home to a few thousand moose and 20-50 wolves. Wildlife scientists have studied the island's food chains for years. During the 1980s, scientists noticed that as the old moose population increased; the number of wolves increased, and as the number of old moose decreased, the number of wolves decreased. What conclusion is best supported by this passage?
What is F- Wolves prey on older moose.

The annual goal of the Preservation Middle School Environmental Club is to reduce the amount of solid waste it contributes to the landfill by collecting and composting food waste from the school cafeteria. Students then collect humus from the compost bins and add it to the planters in the school courtyard. This composting is an example of —
What is C- cycling of matter

Mushrooms and bacteria serve an important role in an ecosystem, that of the decomposer. Why are decomposers important to the ecosystem?
What is F-They release stored energy and allow nutrients from dead organisms to be cycled back into the ecosystem.

Compost bins are containers where items such as food scraps, paper, and yard trimmings are combined with water and air, and are allowed to break down and decompose. This produces a nutrient-rich product that can be used for fertilizer. What happens to the energy from these materials as they decompose?
What is D-Some of the energy is released as heat.

Essentially, biomass is stored ________ energy that man can convert to electricity, fuel, and heat. Through _________, the energy from the Sun is stored in the plant material.
What is G-Solar; photosynthesis

You enter the classroom and you see a laboratory procedure, a glass beaker with a blue liquid in it, a pipette, a glass graduated cylinder, a glass petri dish, leaves, and goggles on your laboratory table. Based on the above scenario, what is the first thing you should do prior to beginning the investigation?
What is C-Wait for teacher directions

A local garden center makes their own compost to fertilize their plants. The owner uses collected rain water in her compost bin. Due to a drought, she would like to know if the type of water used will make a difference for the plants. She asked the local garden club to design and implement an investigation. Which of the following hypotheses best tests the garden club's investigation?
What is H- If tap water is used in a compost bin, then the plants will be negatively affected when fertilized with the compost.

A container that holds organic matter while it is decomposed by fungi and bacteria, converting it into soil.
What is Compost Bin
500
Organisms such as bacteria and fungi that break down the remains of dead plants and animals, without need for internal digestion.
What is Decomposers
