Answer:
Soooooooooooooo the examples of secondary consumers include bluegill, small fish, crayfish and frogs.
Explanation:
The way economists would probably explain the wastage of
this clam resource is by saying that clams are free goods and are therefore
subject to the tragedy of the commons effect. The tragedy of the commons effect
is a theory in economics, postulated by the Victorian economist William Forster
Lloyd.
The tragedy of the commons effect describes a condition
within a shared-resource system where each user act freely according to their
own self-interest, but their collective actions ends in the depletion or spoilage
of that resource, thus having a negative impact on the common good of all users.
In this case, commons is taken to refer to the clam resources.
<h2>Basic research is the least likely to result in product innovation that have near-term commercial application</h2>
Explanation:
Basic research, is otherwise called pure research. This is the first step in production innovation. This is followed by "applied research", then "innovation development", then to go for "production-sales-market".
The information gathered here will be very light or a starter. It is not possible to foresee all the outcomes or the benefits which is achieved in the basic research.
We cannot even predict the types of research knowledge which might add a value to the future changes
Answer:
Expected contribution as per sales mix = $37*0.60 + $50*0.40
= $22.20 + $20
= $42.20 per unit
Total number of products in total at break even point = Total fixed cost / Contribution per unit
= $227,880 / $42.20 per unit
= 5,400 units
How many units each of Super and Supreme must Adams sell to break even?
<u>According to sales mix:</u>
Super = 5,400 * 60% = 3,240 units
Supreme = 5,400 * 40% = 2,160 units.
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.
