Let us look at the what, why and how of studying extreme places like the deep earth and the deep space. Scientists need to figure out as to 'what' they want to look at such places, be it a new exotic creature or bio-genesis (birth of life). Unless there are several testable hypothesis constructed, such a study cannot begin. The 'why' aspect deals with the purpose of such research and expeditions. Is it of any use to the humans, or will it improve our current understanding of a phenomenon? The 'how' aspect deals with the technology and the economic assistance that can help in undertaking such a research. All these are the challenges that needed to be thoroughly considered to make such a research or expedition possible.
Ecosystems can be large and are made of biomes. Some examples of ecosystems are deserts and forests.
<span>Muscle cells are uniquely adapted to contractile function due to three main things. FIrst, they have a large capacity for storage of readily available glycogen to use for work. Second, they contain the actin and myosin cross-bridge cycling structure to perform a contraction of a muscle fiber. Finally, each fiber has central nervous innervation to control contraction and relaxation of the muscle fibers.</span>
<h2>Competitive exclusion principle.</h2>
Explanation:
The fundamental and realized niches of B. balanoides are identical, but the fundamental and realized niches of C. stellatus are different.
All the possible combination of resources and condition under which a species can grow, survive and reproduce is called its fundamental niche. Whereas, the more limited set of resources and condition under which a species can grow, survive and reproduce in the presence of competitors and predators is termed as its realized niche.
Competitive exclusion principle states that if two competing species coexist in a stable, homogeneous environment, then they do so as a result of differentiation in their realized niche.
<em>B. balanoides</em> can use a wider range of resources than<em> C. stellatus </em>because its fundamental and realized niches are identical . Hence thrives to exclude C.stellatus.
