Question

1. the sumatran orangutan is critically endangered due to: a. habitat loss from deforestation b. overfishing c. climate change d. pollution 2. what term describes the pattern of distribution where individuals are randomly arranged in an ecosystem? a. clumped dispersion b. uniform dispersion c. random dispersion d. linear dispersion 3. what characterizes commensalism in symbiotic relationships? a. one benefits, the other is harmed b. both species are harmed c. one benefits, the other remains unaffected d. both species benefit

Explanation:

1. Deforestation - related habitat loss is a major threat to Sumatran orangutans. Overfishing doesn't directly impact them. Climate - change and pollution are factors but habitat loss is the most critical.
2. Random dispersion is defined as the random arrangement of individuals in an ecosystem. Clumped dispersion is when individuals are grouped together, uniform dispersion has a regular pattern, and linear dispersion is not a standard ecological term for this context.
3. In commensalism, one organism benefits while the other is neither helped nor harmed. One - benefits - the - other - is - harmed is parasitism, both - are - harmed is amensalism, and both - benefit is mutualism.

Answer:

1. a. Habitat loss from deforestation
2. c. Random dispersion
3. c. One benefits, the other remains unaffected
