Question

this graph shows population size and time. what model of growth does this graph represent? exponential growth environmental resistance growth logistic growth steady growth what is an example of a community? a penguin sanctuary a man - made pond stocked with catfish a natural pond with fish, turtles, frogs, and ducks a high school campus

Explanation:

For the first question, exponential growth is characterized by a J - shaped curve where the population size increases rapidly over time, which matches the given graph. Logistic growth has an S - shaped curve with a leveling - off phase due to environmental limits. Environmental resistance growth is not a standard term for this context, and steady growth implies a constant rate without the rapid acceleration seen here.
For the second question, a community is an assemblage of different populations of organisms living in the same area. A natural pond with fish, turtles, frogs, and ducks contains multiple species interacting in the same habitat, making it a community. A penguin sanctuary mainly has penguins (a single - species focus), a man - made pond stocked with catfish is mainly about catfish (also single - species focus), and a high school campus is a human - made environment and not a biological community in the ecological sense.

Answer:

1. A. Exponential growth
2. C. A natural pond with fish, turtles, frogs, and ducks
