Answer:
Explanation:
A keystone species is the one which plays an important role in maintaining the structure of the ecosystem. On the keystone species many other species of the ecosystem are dependent upon.
The potential effects associated with the keystone species includes the following:
1. No other species will be capable of filling the same ecological niche. Hence, the dependent organisms will suffer and the ecosystem will change drastically.
2. The ecosystem will be populated by the invasive species which will affects the population of native species.
Answer:
Incisors: 1. These teeth help in biting the food. 2. They are total 8 in number- four in each jaw. Canines: 1. These teeth help in tearing the food. 2. They are total 4 in number- 2 in each jaw.
I think the conclusion would be that the fundamental and realized niches of B. balanoides are identical, but the fundamental and realized niches of C. stellatus are different.A barnarcle is a type of arthropod constituting the infraclass Cirripedia in the subphylum Crustecea, and thus related to crabs and lobsters. B. balanoides is a barnacle that attaches to rocks, especially during intertidal zones while C.stellatus is a species of acorn barnacle common on rocky shores in south West Eangland, Ireland, and Southern Europe.
