What might happen if an organism in an ecosystem is removed?
Removing one piece can destabilize the entire system depending on the role of the removed organism. Could lead to overpopulation, or extinctions of other species.

Why is ecology important to humans?
Ecology is important to humans because it gives us info on the difference between people and nature and that's very crucial for producing food.

DOUBLE POINTS (positive or negative) POSSIBLE:
What is predation? What is competition? How are they types of symbiosis?
Predation is when one organism kills and eats another organism.
Competition is a direct or indirect interaction between organisms that vie for a limited resource, such as food, water, or space.
Predation and competition are considered types of symbiosis because they represent close interactions between different species within an ecosystem, even though one organism is negatively affected by the relationship.
