Introduction:
Ecological community is the naturally occurring group of plants, animals that are interacting in a unique environment. Ecological community structure and composition depends upon environmental factors such as altitude, soil, climate, and water availability.
Answer to Problem 1MCQ
Correct answer:
Many types of microbes live in a human intestine. This is the only option which explains the concept of ecological community correctly Therefore, option a. is correct.
Explanation of Solution
Reason for the correct statement:
Ecological communities are those communities in which an organism interacts in a unique environment without harming each other. Different types of microbe living in human intestine shows an example of ecological community.
Option a. is given as “The many types of microbes living in a human intestine”.
As, “Ecological communities means organisms living in a unique environment without harming other organism and environment, microbes living in human intestine”, is the right answer.
Hence, option a. is correct.
Reasons for the incorrect statements:
Option b. is given as “an ant colony”.
An ant colony is community of a single type of organism in which there is no interaction between other organisms. So, it is a wrong answer.
Option c. is given as “the people living in your neighborhood”.
People living in neighborhood are an example of social community. Where people are living together but are not dependent on each other. So, it is a wrong answer.
Option d. is given as “the cells of a platypus”.
A cell of the platypus does not show any interaction with other organism or cells. So, it is a wrong answer.
Hence, option b., c., and d. are incorrect.
Ecological community means organisms living in a unique environment without harming other organism and environment.
