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.
