A) All members of a species in an area
B) All organisms in an ecosystem
C) All the humans in an area

Human activity in an ecosystem that affects population growth of other organisms is an abiotic factor
False
What does "carrying capacity" mean?
The largest population that can be supported in an area without destroying the habitat.
The lynx mostly eats hares. When there is lots of food, more lynx can survive. When there are less hares, more lynx will starve and die.
The greater the number of prey animals, the greater the number of predators AND the lower the prey population, the lower the predator population.
What does "limiting factor" mean?
What are the levels of organization in an ecosystem, starting from the smallest to largest? Hint: "organism" is the smallest.
Organism, population, community, ecosystem
"Carrying capacity" is the largest number of all organisms that an ecosystem can support.
False (It's the largest number of organisms of *one species* an ecosystem can support)
