Problem: - The animals living in the forest have fewer places to hide - Predators can now find their prey eaiser - Birds will fly away from the area - Waters warm up which hurts the fish swimming in them. What might be the first step of the process?

A: Forest fires burn forests

Problem: - The light energy is used to convert carbon dioxide - The plant uses nutrients in the soil - The plant uses carbon dioxide in the air to produce glucose - The plant uses the glucose to give itself energy - Oxygen is released as a by product. What might be the first step of the process?

A: Light energy is absorbed by chlorophyll in a plant

Problem: - The oxygen travels to the lungs through the windpipe - The air sacs in the lungs send the oxygen into the blood stream - The carbon dioxide in the blood stream is transferred to the air sacs - The lungs expel through the nose or mouth back into the environment. What might be the first step of the process?

A: You breathe oxygen into your body through the nose or mouth

Problem: - Your stomach digests the food - Sugars from food enter your bloodstream - Insulin helps turn sugars into energy - Insulin helps your body store the energy in fat, muscle and liver cells - What might be the first step of the process?
