1 multiple choice 1 point which answer choice best describes a community? roosting mother bats recognizing their offspring praying mantises caring for their young different species of lizards occupying the same niche (role/job)in a desert three - spined sticklebacks living in estuaries 2 multiple choice 1 point which is the best example of commensalism? a mosquito feeding on human blood remora fish riding on a shark for transport

Explanation:

1. A community is all the different populations of organisms living in a particular area. Three - spined sticklebacks living in estuaries represent a group of organisms in a specific habitat which is a community. Roosting mother bats recognizing their offspring and praying mantises caring for their young are more about parental - offspring relationships. Different species of lizards occupying the same niche is about competition and niche concepts rather than a community description.
2. Commensalism is a symbiotic relationship where one organism benefits and the other is neither helped nor harmed. A remora fish riding on a shark for transport benefits from the movement and access to food scraps, while the shark is not affected. A mosquito feeding on human blood is parasitism as the human is harmed.

Answer:

1. Three - spined sticklebacks living in estuaries
2. Remora fish riding on a shark for transport
