The Life of Goats
Have you ever eaten goat cheese before? Goat cheese is made from a goat's milk. Some people say that it is the healthiest cheese. It helps you to keep your bones strong and is easy to digest.
Goats like to eat everything they find! They get vitamins and nutrients when they eat the leaves from trees or grass from the ground. They also like to eat fruits and vegetables. When goats eat healthy they grow big and strong, and also to produce milk.
When goats pass away, bacteria and fungi break down the goat and return its nutrients to the soil, which can supports plant growth.
Question:
Represent the transfer of energy when a person eats goat cheese by explaining the order of energy transfer between goats, plants, and people.

Farmers use tools to loosen the soil before planting seeds so that the soil is not as compact. The theory is that loosening the soil will make more space for the roots to grow, as well as be able to access both water and air.
A professor worked with a team of scientists to study this practice. They set up an experiment where they planted sunflower seeds. Once the seeds had all sprouted, they separated the plants into different boxes, and each box had a different condition. They took notes about their boxes and how the plants grew in each one.
The scientists also took pictures of the growth of the roots. They first took a picture of the starting roots. Then, after the experiment, they took pictures of the roots from two plants in each box and made the chart below.
A. Increasing air in the soil helps plants to grow and be healthy.
B. The looser the soil is, the more we need to water the plants.
C. The more compact the soil is, the more air there is in the soil.
D. Plants need 2 ounces of water each day to be healthy and grow.
A. Increasing air in the soil helps plants to grow and be healthy.

Imagine you are studying about plankton. Plankton are organisms that live in oceans. You find the following chart that explains the two major types of plankton that exist. Analyze the chart and answer the questions below.
Based on the information in the table, how are the hydrosphere and biosphere interacting?
Hydrosphere: water
Biosphere: habitat for the phytoplankton and zooplankton

Mrs. Gallo wants to help Mrs. Hamilton make a model to show how energy transfers in water environments. Mrs. Gallo wants to end with fish, but needs help for the rest of the model.
What best describes the energy transfer in this environment amongst fish, zooplankton, phytoplankton, and the sun?
Provide a reason for your claim.
Sun- Phytoplankton- Zooplankton-Fish

If a new species of plant were to be introduced to a different ecosystem, how would that affect the ecosystem for the organisms that were already native to the area?
The new species would become harmful to the native organisms and threaten the animals and plants.

Explain how energy transfers between the wolf, plant, rabbit, and sun.
The sun gives energy to the plant. The rabbit eats the plant and the wolf gets energy from the rabbit by eating it.
