Answer:
The options are given below:
A) competitively exclude other predators.
B) prey on the community's dominant species.
C) allow immigration of other predators.
D) reduce the number of disruptions in the community.
E) prey only on the least abundant species in the community.
the correct option is B
Explanation:
Keystone species refers to a predator which prevents a particular herbivorous species from wiping out the dominant plant species. If the number of prey are low, the keystone predators can be less abundant and still be effective. Keystone species have a disproportionately large effect on its environment relative to its abundance.
Therefore, by preying on a community's dominant species, keystone predators help to maintain the species diversity in the community, because they ensure that the dominant predators do not totally wipe out the various organisms present in the ecosystem.
Answer:
a or b is the answer I am not sure so I gave two options
The answer of the country is now 12.7 and the answer of the year is to 2024
Answer and Explanation:
The computation is shown below:
= (Original cost - residual value) ÷ (useful life)
= ($52,000 - $8,000) ÷ (4 years)
= ($44000) ÷ (4 years)
= $11,000
In this method, the depreciation is same for all the remaining useful life
a. The depreciation expense for 2019 is $11,000
b. The depreciation expense for 2020 is $11,000
c. The accumulated depreciation for year 2019 is $11,000
d. The accumulated depreciation for year 2020 is $22,000 ($11,000 + $11,000)
e. The book value is
= Original cost - accumulated depreciation
= $52,000 - $22,000
= $30,000
