Question

2 a group of organisms that can interbreed to produce fertile offspring
3 conservation status for organisms with a 30 - 50% population decline
4 a group of populations living and interacting with each other in an area
5 conservation status for organisms with greater than 80 - 90% population decline
6 communitys ability to resist change and return to original composition if disturbed

ecosystem
critically endangered
select match

Explanation:

1. An ecosystem consists of a community (living organisms) and its abiotic environment (non - living factors like climate, soil, etc.). So "A community and its abiotic (non - living) environment" matches "Ecosystem".
2. The biological definition of a species is a group of organisms that can interbreed to produce fertile offspring. So "A group of organisms that can interbreed to produce fertile offspring" matches "Species".
3. Vulnerable species are those with a 30 - 50% population decline. So "Conservation status for organisms with a 30 - 50% population decline" matches "Vulnerable species".
4. A community is defined as a group of populations living and interacting with each other in an area. So "A group of populations living and interacting with each other in an area" matches "Community".
5. Critically endangered species are those with a greater than 80 - 90% population decline. So "Conservation status for organisms with greater than 80 - 90% population decline" matches "Critically endangered".
6. Stability in an ecological context refers to a community's ability to resist change and return to its original composition if disturbed. So "Community's ability to resist change and return to original composition if disturbed" matches "Stability".

Answer:

1. Ecosystem
2. Species
3. Vulnerable species
4. Community
5. Critically endangered
6. Stability
