Which of the following is an example of INTRAspecific competition?

1)Two pink anemones need substrate (rock) to attach to on a reef
2)Killer whales and leopard seals both hunt down penguins around Antarctica
3)A grouper and a barracuda both feeding on small snapper
4)Bull kelp and giant kelp absorbing nutrients from the surrounding water in the same kelp forest

1 answer

INTRAspecific competition refers to competition between individuals of the same species.

  1. Two pink anemones need substrate (rock) to attach to on a reef - This is an example of intraspecific competition, as it involves individuals of the same species competing for the same resource.

  2. Killer whales and leopard seals both hunt down penguins around Antarctica - This is interspecific competition, as it involves different species competing for the same resource (penguins).

  3. A grouper and a barracuda both feeding on small snapper - This is also interspecific competition, as it involves different species competing for the same food source (small snapper).

  4. Bull kelp and giant kelp absorbing nutrients from the surrounding water in the same kelp forest - This is also interspecific competition, as it involves different species of kelp competing for the same nutrients.

Therefore, the correct answer is 1) Two pink anemones need substrate (rock) to attach to on a reef.
