Question

1. plants need all of the following except: a. light b. minerals c. water d. high temperature 2. the study of organisms and their environment and how they interact is called what? a. biology b. chemistry c. ecology d. geology 3. organisms that break down dead organisms are called what? a. niche b. decomposers c. autotroph d. secondary consumers 4. the specific job or role of an organism in its ecosystem is called what? a. heterotroph b. habitat c. autotroph d. niche 5. the graph below shows what pattern of population growth? a. explosive b. logistical c. boom and bust d. exponential

Explanation:

1. Plants need light for photosynthesis, minerals for growth, and water for various physiological processes. High temperature is not a universal need as many plants thrive in cooler climates.
2. Ecology is the study of organisms and their environment and their interactions. Biology is a broader study of life, chemistry focuses on matter and its reactions, and geology is about the Earth's physical structure.
3. Decomposers break down dead organisms, recycling nutrients back into the ecosystem. A niche is an organism's role, an autotroph makes its own food, and secondary consumers eat primary consumers.
4. The specific job or role of an organism in its ecosystem is called its niche. A heterotroph gets food from other sources, a habitat is where an organism lives, and an autotroph produces its own food.
5. The graph shows exponential population growth, which is characterized by a rapid, accelerating increase in population size over time.

Answer:

1. D. High Temperature
2. C. Ecology
3. B. Decomposers
4. D. Niche
5. D. Exponential
