The scientific law of one organism feeding off other where energy is transferred from one form to another is known as the law of conservation of energy.
<h3>How the sun is the primary source of energy for ecosystems?</h3>
Energy from the highest energy source that is sun is absorbed by plants to convert it into food (i.e a form of energy). plants are the only ones that can convert sunlight into another form of energy directly.
The animals and organisms that feed off of the plants take some part of this energy for their life cycles and then the animals that feed off of these animals again take some part of this energy and carry on with their life cycle, this is how energy from sun (highest source) is transferred to different organisms by Just changing form.
Thus, The scientific law of one organism feeding off other where energy is transferred.

Answer: Mosses retain soil humidity and prevents its degradation, besides are habitat for little invertebrates.
Explanation: Mosses are non-vascular plants (they don't have conductive vessels as xylem and phloem) that live places as tree trunks, rocks, walls and soils. This habitats must be humids because mosses need water for nutrient transport, because they don't have cuticle (prevents water lost) and for fertilization. Mosses are important for the ecosistems where they live because retain water in the soils thus prevent erosion and harbor invertebrates as Tardigrades (water bears).
