Question

select all the correct answers.

panthers and leopards prey on deer in an ecosystem. for unknown reasons, the population of leopards increased drastically. what are the likely effects of this change on the species?

more food for panthers and more competition for leopards
less food and more competition for panthers
fewer deer and more competition for panthers
more food for deer and less competition for panthers and leopards
more food for leopards and less competition for panthers

Explanation:

Analyze the ecological relationships

Using the Population Dynamics and Limiting Factors knowledge points

• Panthers and leopards share the same ecological niche as predators preying on deer.
• Deer act as a shared limiting resource (food source) for both predator populations.

Evaluate the population change

Using the Population Dynamics knowledge point

• The population of leopards increases drastically.
• A larger leopard population consumes more deer, reducing the overall deer population.

Determine effects on panthers

Using the Limiting Factors knowledge point

• Fewer deer means less food is available for panthers.
• Increased demand for the same limited food source leads to more intense competition for panthers.

Evaluate the given options

• "more food for panthers and more competition for leopards": Incorrect, food decreases for panthers.
• "less food and more competition for panthers": Correct, as deer numbers drop.
• "fewer deer and more competition for panthers": Correct, because more leopards consume more deer, raising competition.
• "more food for deer and less competition for panthers and leopards": Incorrect, deer are prey, not consumers of predators.
• "more food for leopards and less competition for panthers": Incorrect, food per leopard actually decreases and competition increases.

Answer:

• more food for panthers and more competition for leopards
• less food and more competition for panthers (Correct answer)
• fewer deer and more competition for panthers (Correct answer)
• more food for deer and less competition for panthers and leopards
• more food for leopards and less competition for panthers
