Answer:
Animals release carbon dioxide into the air, and plants take it in. 
Explanation:
The existence of plants and animals on the planet is important in maintaining life. Animals release carbon dioxide as waste through the respiratory system. The carbon dioxide that is released is then taken in by plants, which they use to produce their own food through a process called photosynthesis. The by product of that process is oxygen which is released in the atmosphere and animals take it in. 
 
        
             
        
        
        
Answer:
Invertebrates have a very quick life cycle and die very easily, as a result, they evolve very quickly into many different types of animals. also, they are often very small and their ecosystems are subject to much quicker change than that of vertebrates, meaning that mutations in their genes become relevant more often. Many invertebrates span very large areas (sea animals span most of the oceans, insects span entire continents) and so they evolve to be different species in different places.
Or
They do not have bones, they live on water or land, they can have soft bodies or exoskeletons, and others are parasites.

Answer:
 Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.     Protein must be broken down into amino acids.     Starches break down into simple sugars.     Fats break down into into fatty acids and glycerol.

Let's do this by process of elimination: A cannot be the answer because glucose is broken down, not built up or synthesized. B is ruled out for the same reason. D is incorrect because transpiration results in water loss, not energy gain. The only correct answer choice is C respiration, specifically by the process of substrate-level phosphorylation during glycolysis in order to break down glucose into two pyruvate molecules and two net ATP
