Which one of the following is the most inclusive category? a) ecotone. b) landscape. c) ecosystem d) biotic community

C) ecosystem

Explanation:

Ecosystem is a biotic community where living things such as plants, animals, humans, birds, insects and others interact with the non-living components of the environment. An ecotone is the transition zone between the two biomes. It is the zone where the two communities meet. Thus this can be a part of the ecosystem. A landscape is the abiotic factor which also be the part of the ecosystem.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
