Question

what is a significant impact of deforestation on ecosystems?
a. disrupting habitats and reducing biodiversity
b. enhancing oxygen balance
c. decreasing carbon dioxide levels
d. encouraging biodiversity

what is the primary role of abiotic components in an ecosystem?
a. they provide food for herbivores
b. they are responsible for energy flow
c. they include non - living factors like water and sunlight
d. they are the living organisms within the ecosystem

which level of ecological organization involves multiple individuals of the same species?
a. ecosystem
b. population
c. individual
d. community

Explanation:

• First question: Deforestation destroys habitats, leading to a loss of species and reduced biodiversity. Trees absorb carbon dioxide and release oxygen, so deforestation would not enhance oxygen balance (b) or decrease carbon dioxide (c). It also does not encourage biodiversity (d).
• Second question: Abiotic components are non - living factors like water and sunlight (c). They do not provide food for herbivores (a) (that's the role of producers). Energy flow is mainly related to biotic components' interactions (b). Living organisms are biotic components (d).
• Third question: A population is defined as multiple individuals of the same species in a given area. An ecosystem (a) includes biotic and abiotic components. An individual (c) is a single organism. A community (d) is multiple populations of different species.

Answer:

a. Disrupting habitats and reducing biodiversity
c. They include non - living factors like water and sunlight
b. Population
