part 9


Part 9 is about the carbon cycle and how it helps autotrophs and heterotrophs. In the carbon cycle process carbon molecules are made and Autotrophs and heterotrophs use these molecules for growth and energy. Part 9 also is about how plants, lawns,houseplants, and garden need nitrogens but they don't get their nitrogens from the air they get it from the soil because in the soil it has been converted into more usable forms.

Key terms

Autotrophs ~ organism that creates its own food through photosynthesis

heterotrophs ~ It can't create its own food and eats other organism

energy ~ usable power that comes from heat, electricity, etc

nitrogens ~ common element in our galaxy and the Solar System and makes up about 78% of earth's atmosphere.

photosynthesis ~ the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.

carbon dioxide ~ a colorless, odorless gas produced by burning carbon and organic compounds and by respiration and is absorbed by plants in photosynthesis.

fertilizer ~ a chemical or natural substance added to soil or land to increase its fertility

bacteria ~ a member of a large group of unicellular microorganisms that have cell walls but lack organelles and an organized nucleus, including some that can cause disease.

3. this is about process of photosynthesis

In my opinion, this unit is relevant to my everyday life because we need photosynthesis to give plants food,which the animals eat the plants, then we eat the animals. If the plants don't get energy that the sun convented carbon dioxide gas into energy-rich carbon molecules then the animals don't get any food then they die and with no animals to eat we die.

Test Questions

1. what if the photosynthesis stop, what would happen to the plants.

2. Why can't the plants not get nitrogens from the air.

3. DO yo think we can live with without autotrophs.

4. How come Heterotrophs can not make their own food.

5. What happen to carbon when autotrophs and heterotrophs  use the carbon molecules for energy.

6. What percent is nitrogens in earth's atmosphere?

7. In the carbon cycle what does it started with, autotrophs or heterotrophs.

8. What if somebody asked you what was the carbon cycle is. How would you explain it.

9. Compare and contrast autotrophs and heterotrophs.

10. What does a heterotrophs do
