I think it is keystone.  If they were not there the population of urchins would go up and the kelp would go down.

Natali5045456 [20]
Downstream river would have less water, so there would be less fish to catch.

River re-routing is a process wherein the mouth of the river is mouth to another location. Thus, existing mouth of the river will lose its water source and have less water. Fishes in the existing river path will decrease because of the decreased level of water.

Which characteristic distinguishes fungal cells from plant cells
sertanlavr [38]

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>
