Answer: Sea otter is the pioneer species in the kelp forest as it regulates and controls the population of other species in the kelp forest.
Explanation:
If sea otters are hunted and their population is brought to extinction then this will cause major harm the ecosystem of the kelp forest and it will disturb the ecological balance in the kelp forest. The herbivorous animals consumed by the sea otters will increase in population and they will consume a lot of vegetation in the forest. The kelp forest which forms the coastline will not remain effective in providing protection against the storms to the neighboring areas.

Neutrons
Explanation:
Atoms of the same elements are called isotopes. They differ from other atoms in the number of neutrons they posses. They share the same chemical properties but only differ with regards to their mass number.
- Isotopy is a phenomenon whereby an atom of an element exist in more than one form but they have the same atomic number.
- Atoms of such element only differ in the number of neutrons they contain.
- Since the mass number of an atom is the sum of protons and neutrons, they differ in this number too
- Isotopes have the same chemical properties.

OC=2
From the question we are told
A city government received a $1 million grant to build swimming pools and skating rinks for youth. based on the data provided in the graph, what is the opportunity cost of building one swimming pool?
Generally the equation for the Opportunity cost is mathematically given as
Therefore
From the graph of the question we can ascertain that Opportunity cost
OC=2
