When we're eating food, the different food stuffs need to be broken down from big molecules to smaller ones. This happens through different processses which happen in our body. For this reason, the larger molecules need energy to be broken up into smaller ones and when these happens these smaller ones get then taken up in our body and used up.
Answer: Feeding behaviors, trophic levels, cell wall composition, and their organelles distinguish fungi from plants.
Explanation:
While plants and fungi are both eukaryotes, they differ in terms of feeding behaviors, trophic levels, cell wall composition, and their organelles.
- Cell walls: both are non-chain polysaccharides (sugars) that function as structural support; yet fungal cell walls are composed of chitin while plant cell walls are made up of cellulose
- Feeding: fungi secrete compounds that digest their food sources before they can take in nutrients and they store food as <em>glycogen; </em>while plants do not require a means of pre-digesting food and store their food as <em>starch.</em>
- Organelles: plant cells contain <em>chloroplasts</em>, small green structures with chlorophyll that causes their characteristic coloration. Unlike plants, fungi do not photosynthesize to make their own food or contain chloroplasts.
- Trophic level: are strictly <em>heterotrophs or decomposers, </em>depending on other organisms for survival. Their chloroplasts enable them to carry out photosynthesis, thus they are <em>autotrophs or producers. </em>
Some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as:<u> vestigial structures</u>.
Vestigial structures are organic structures that do not appear to fulfill any important biological function in the organism that possesses them.
- These structures are preserved as an inheritance of the evolutionary process, because at some point in the history of evolution an ancestor of the current species had that structure.
- These types of structures, which can be bones, organs, structures in the skin or any other part of the body, no longer offer any meaningful function for the body.
- The presence of vestigial structures in animals is considered proof that evolution and natural selection exists.
Therefore, we can conclude that some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as vestigial structures.

Answer:
The two organisms are in a predator-prey relationship.
Explanation
because the hawk is the predator, it ate the mouse, and th mouse was they prey, it was eaten
