Biological communities evolve through ecological succession. Ecological succession is the change in the structure and composition of species in a specific ecological community over time that can be observed. Ecological succession can occur as a natural process of time, or it can be instigated by a sudden event, a wild fire, for example. There are natural changes that occur that effect the species type and variation that exists and thrive in the communities.
Answer:
velocity = 3 m/s
Explanation:
kinetic energy = 1/2 * mass(kg) * velocity²
Using the formula:
18 = 1/2 * 4 * velocity²
9 = velocity²
velocity = 3 m/s
Migratoin is not always temporary so the anser is false
