Question

1. name and explain each of the three types of symbiosis.

Explanation:

1. Mutualism: A symbiotic relationship where both species involved benefit. For example, bees and flowers—bees get nectar for food, and flowers get pollinated to reproduce.
2. Commensalism: A symbiotic relationship where one species benefits, and the other is neither helped nor harmed. An example is barnacles on whales—barnacles get a place to live and move to new food sources, while whales are unaffected.
3. Parasitism: A symbiotic relationship where one species (the parasite) benefits at the expense of the other (the host), which is harmed. For example, ticks on dogs—ticks feed on the dog's blood, potentially causing disease or discomfort to the dog.

Answer:

1. Mutualism: Both species benefit. E.g., bees & flowers (bees get nectar, flowers get pollinated).
2. Commensalism: One benefits, the other is neutral. E.g., barnacles on whales (barnacles benefit, whales are unaffected).
3. Parasitism: One (parasite) benefits, the other (host) is harmed. E.g., ticks on dogs (ticks feed on dog’s blood, harming the dog).
