When hermit crabs crawl across the ocean floor, they often have sea anemones attached to their backs. The anemones use their dangerous tentacles to keep hermit crab predators at bay, and they dine on the particles of food that the crab does not eat. This is an example of:

a. bioremediation.
b. alternation of generations.
c. endosymbiosis.
d. symbiosis.

Option D) Symbiosis

When hermit crabs crawl across the ocean floor, they often have sea anemones attached to their backs. The anemones use their dangerous tentacles to keep hermit crab predators at bay, and they dine on the particles of food that the crab does not eat. This is an example of symbiosis.

Explanation:

Symbiosis is a biological relationship between two organisms whereby both benefits food, shelter, protection etc, from each other.

In this case, hermit crabs derive protection from the sea anemone, while the latter derives food from the hermit crabs.

Thus, both hermit crabs and sea anemones benefits, showing symbiosis

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
