- Note: Since you have posted a question with multiple sub-parts, we will solve the first three sub-parts for you. To get the remaining sub-part solved please repost the complete question and mention the sub-parts to be solved. Carrying capacity: The resources present in the ecosystem are utilised by all the organisms that grow and thrive in the ecosystem. Since the resources present are limited the environment can support only a limited number of organisms. The maximum number of organisms that the environment can support is called the carrying capacity. Above the carrying capacity, there is completion for the limited resources. Step 2 1. When we see the data representing the deer population from 1905-1939 we see that there has been a rapid increase in the deer population initially and then the population falls down drastically. In the year 1915 The carrying capacity for the Kaibab deer population was 30.000 deers for 30,000 hectares of land. If the see the deer…arrow_forwardSubmit your project researching an ecosystem you would find in your state. You may submit a poster, presentation, link to your created website, or other document.
