The sea snails in tidal marine areas feed on the dominant species of algae. what kind of interaction takes place between the sea snail and the algae a) mutualism b)predation c)competition d)parasitism

The correct answer is B. Predation

Explanation:

In ecosystems, one of the most common interactions between organisms is predation, this occurs when one organism feeds on others. This type of interaction includes a predator (organism killing and eating another organism) and prey (an organism that is being killed). Additionally, in predation is the predator the one that benefits completely, although this relationship is necessary to regulate the population of the prey. In the case presented, predation occurs because the sea snail eats the species of algae and therefore the seasnail is the predator while the algae are the prey.

explanation:

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
