These pesticides don't just affect those organisms that are targeted, but even the users and other organisms that may have come in contact with pesticides.

<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.
Answer: Option A and B.
Archaea and bacteria are prokaryote and reproduce by binary fission.
Explanation:
Archaea are grouped of single celled organisms that have no cell nuclei. They are prokaryotes and reproduce by binary fission. They were formally grouped as bacteria with the name archaeabacteria but the classification is outmolded. They are now renamed as archaea bacteria as they are closely related to eukaryotes.
Bacteria also are single celled, microscopic organisms. They are prokaryotes and they reproduce by binary fission. They have are number of shapes ranging from spheres to rods.
