Question

create a tolerance graph similar to the tolerance of steelhead trout figure in your book. title your graph tolerance of plant a. label the zones. then label the limits of each zone according to the facts about plant a listed below. can live at an elevation between 1,000 and 2,000 m cannot live above 6,000 m can live at an elevation between 5,000 and 6,000 m grows best between 2,000 and 5,000 m cannot live below 1,000 m get it? compare and contrast a habitat and a niche. describe mutualism, commensalism, and parasitism by providing an example of each term. 1. 2. 3.

Explanation:

1. Habitat vs Niche: A habitat is the physical place where an organism lives, like a forest for a deer. A niche is the role an organism plays in its environment, including its interactions with other species and its use of resources. For example, a deer's niche includes what it eats (herbivory), when it is active (crepuscular), and how it interacts with predators.
2. Mutualism: It is a symbiotic relationship where both species benefit. An example is the relationship between bees and flowers. Bees get nectar for food, and in the process, they help flowers by pollinating them.
3. Commensalism: A symbiotic relationship where one species benefits and the other is neither helped nor harmed. For instance, barnacles attaching to whales. The barnacles get a place to live and access to food - rich water as the whale moves, while the whale is not affected by the barnacles' presence.
4. Parasitism: A symbiotic relationship where one species (the parasite) benefits at the expense of the other (the host). Tapeworms living in the intestines of animals are parasites. They absorb nutrients from the host's digestive system, causing harm to the host.

Answer:

1. Habitat is the living - place, niche is the role.
2. Bees and flowers (mutualism).
3. Barnacles on whales (commensalism).
4. Tapeworms in animals' intestines (parasitism).
