Answer 1

1.) d.) living organism and their environment. (Ecology is a science which study living things their environments and their interactions)

2.) d.) habitat destruction ( human activity destroys the habitat of species which is needed for their survival leads to endangered species)

3.) a.) producers (plants and algae produces their own food through photosynthesis and are kept at the base of pyramid and are called producers. Producers to primary consumers to secondary consumers to tertiary consumers are the levels in pyramid. Decomposers are kept at the side of pyramid as they decompose the dead for nitrients)

4.) d.) have different ecological niche. ( all the 3 bird species have different living conditions)

5.) a.) carnivores

6.) b.) decomposers ( detrivores feed on dead and other name is decomposer)

7.) e.) all are correct

8.) e.) protein - nucleotides ( amino acids are the building blocks of proteins and not nucleotides)
