What are the 4 major types of Systems of Spheres

We call these four subsystems "spheres". Specifically, they are the "lithosphere" (land), the "hydrosphere" (water), the "biosphere" (living beings) and the "atmosphere" (air). Each of these spheres can be divided into sub-spheres.

Geographers break down the Earth's systems into four spheres that make up the world's air (atmosphere), water (hydrosphere), land (geosphere), and living organisms (biosphere).

Explanation:

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
