1.Describe how a population differs from a community using your own examples.
2.Describe how an ecosystem differs from a community using your own examples.
Please please help. thanks.
A population is a group of the same organisms living together in one area
A community is a group of different organisms living together in one area and relying on each other and working together
Since this is not my area of expertise, I searched Google under the key words "population community ecosystem definition" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. Thanks for asking.
1. A population is a group of individuals of the same species living in the same area at the same time. For example, let's consider a population of lions in a particular savanna. In this case, the lions represent the population because they are a group of individual lions living in the same area at the same time.
On the other hand, a community refers to all the populations of different species living and interacting with each other in a specific area. For instance, in the savanna, in addition to the population of lions, there may be populations of zebras, elephants, gazelles, and various other animals. Together, all of these populations make up the community because they are different species coexisting and interacting with each other in the same area.
In summary, a population represents a group of individuals of the same species, while a community includes all the populations of different species in a particular area.
2. An ecosystem differs from a community in that it includes all the living organisms (community) as well as the physical environment they interact with. For example, let's consider a coral reef ecosystem.
In the coral reef ecosystem, the community would consist of all the different species of fish, sea turtles, corals, and other organisms that live and interact with each other in that specific area.
However, the ecosystem also includes the physical and non-living components such as the water, sunlight, temperature, and the coral reefs themselves. These physical components play a vital role in shaping the interactions and dynamics of the community.
Essentially, while a community focuses on the populations of different species and their interactions, an ecosystem encompasses the community as well as the physical environment in which it exists.
To summarize, a community represents the populations of different species interacting with each other in an area, while an ecosystem includes the community along with the physical environment.
