Which of these represents the levels of organization, from smallest to largest?(1 point)
community, ecosystem, organism, population
organism, population, community, ecosystem
ecosystem, community, population, organisms
population, organism, ecosystem, community
The correct order of levels of organization, from smallest to largest is: organism, population, community, ecosystem.
To determine the correct answer, we need to understand the levels of organization in ecology. The levels of organization, from smallest to largest, are as follows:
1. Organism: This level refers to an individual living entity, such as a plant, animal, or human being.
2. Population: A population is a group of individuals of the same species that live in the same area and can potentially interbreed.
3. Community: A community is an assemblage of different populations of organisms that live in the same area and interact with each other.
4. Ecosystem: An ecosystem is a community of organisms and their physical environment, including all the interactions between them.
Now, let's look at the answer choices:
A. community, ecosystem, organism, population - This order is incorrect. It starts with the community, which is larger than the population and the organism, and then jumps to the ecosystem.
B. organism, population, community, ecosystem - This order is correct. It starts with the smallest unit, the organism, and progresses to larger units, ending with the ecosystem.
C. ecosystem, community, population, organisms - This order is incorrect. It starts with the largest unit, the ecosystem, and goes down to the population and then the organisms, but it jumps over the community.
D. population, organism, ecosystem, community - This order is incorrect. It starts with the population and the organism, but then jumps to the ecosystem without including the community.
Therefore, the correct answer is B. organism, population, community, ecosystem.
