Seagrasses are flowering plants which grow in the photic zones of marine environments. which factor would be a biotic limiting factor for seagrass growth?
density of animal population
or
concentration of dissolved nutrients

Density of the animal population Animal population is the only biotic or living factor. Grazing by herbivores, like sea turtles, will affect seagrass populations. Too many herbivores, not enough segrass.

Density of animal population

Explanation:

The seagrasses are the photosynthesizing plants that grows in the photic zone as well as these are anchored by the mud or sand as they can be grown in the submerged condition. Most of these species undergoes pollination and complete their life cycle underwater. The biotic limiting factor can be define as the factor which limits the growth and abundance of the population of the species. This limiting factor is the biological agent like plant, animal or insect. In the given situation the density of animal population is the suitable option.

it's not c. i took the quiz and got it wrong. so my best guess is b.

have a great day, and hope this .
