Question

how does overcrowding affect organisms in an ecosystem? * 1 point it increases available resources it leads to greater competition for resources it improves survival rates it eliminates predators

Explanation:

• Option 1: Overcrowding means more organisms competing for the same limited resources, so resources don't increase. Eliminate this.
• Option 2: In an overcrowded ecosystem, organisms (of same or different species) compete more for food, water, space, etc. This makes sense.
• Option 3: Overcrowding and increased competition usually lower survival rates (due to resource scarcity, stress, etc.), not improve. Eliminate this.
• Option 4: Overcrowding doesn't directly eliminate predators; predators are part of the ecosystem and overcrowding affects prey-predator dynamics differently, not elimination. Eliminate this.

Answer:

B. It leads to greater competition for resources
