oa organisms
ob abiotic factors
oc biotic factors
od species

1. which of these is an example of a biotic factor in an ecosystem?

oa animal waste
ob air pressure
oc water currents
od temperature

1. which of these best explains how a population is different from a species?

oa a species can be made up of many populations in various places
ob a population can be made up of many species in various places
oc species are limited by the ability to reproduce fertile offspring and populations are
not
od populations are limited by the ability to reproduce fertile offspring and species are
not

1. which of these is not an or

oa a human
ob an ant
oc an ivy plant

Explanation:

• Question 5: A population is a group of individual organisms of the same species living in a particular area. Abiotic factors are non - living things (like rocks, air), biotic factors are living or once - living things (but population is specifically about organisms), and species is a broader taxonomic category.
• Question 6: Biotic factors are related to living organisms. Animal waste is from a living organism (biotic), while air pressure, water currents, and temperature are abiotic (non - living) factors.
• Question 7: A species is a group of organisms that can interbreed and produce fertile offspring. A population is a group of organisms of the same species in a specific area. So a species can have multiple populations in different places.
• Question 8: The question seems incomplete. But assuming it's about organisms, a human, an ant, and an ivy plant are all organisms.

Answer:

1. A. Organisms
2. A. Animal waste
3. A. A species can be made up of many populations in various places
4. (Incomplete question. If it's about which is not an organism, no valid answer as presented. If it's a typo and for example, if the full question was "Which of these is not an organism?" and assuming no other options, but with given options A, B, C are organisms. If there was a D option like "a rock", then D. But with current info, can't fully answer)
