13. Pictorial examples shown in the W, X, Y, Z boxes
represent levels of ecological organization in a Savanna
Biome. Use the pictures below to answer the following
questions.
Which letter represents a community?
[Choice A] W, a group of one type organism interacting
with an environment
[Choice B] X, many types of organisms interacting with
their nonliving environment
[Choice C] Y, a single lion resting by itself and not
interacting
[Choice D] Z, a group of zebras and wildebeests
interacting
The correct answer is [Choice D] Z, a group of zebras and wildebeests interacting. This represents a community, which is defined as many different types of organisms interacting with each other in a particular area.
The letter that represents a community is:
[Choice B] X, many types of organisms interacting with their nonliving environment
To determine which letter represents a community, we need to understand what a community is. A community is a group of different species living and interacting with each other in a particular area.
Looking at the given options:
[Choice A] W represents "a group of one type organism interacting with an environment." This sounds more like a population, which refers to a group of individuals of the same species living in the same area.
[Choice B] X represents "many types of organisms interacting with their nonliving environment." This suggests an ecosystem, which includes all the living organisms (biotic) and their physical environment (abiotic) interacting with each other.
[Choice C] Y represents "a single lion resting by itself and not interacting." This does not represent a community, as it only involves a single organism and no interaction with other species.
[Choice D] Z represents "a group of zebras and wildebeests interacting." This is the closest representation of a community since it involves multiple species (zebras and wildebeests) interacting with each other.
Based on the definitions provided, the correct answer would be [Choice D] Z, which represents a community.
