Material Cycles: Question 1 of 4
Which life process is classified as autotrophic in some organisms and heterotrophic in other organisms?
  1. hormonal regulation
  2. nutrition
  3. anaerobic respiration
  4. transport

Correct Answer Number: 2

Explanation: The life function of nutrition can be performed by autotrophs, who make their own food (glucose) by processes of photosynthesis or chemosynthesis, or by heterotrophs ,who must ingest, digest, and egest their preformed food (glucose). Heterotrophs can not make their own food.


Material Cycles: Question 2 of 4
Which waste product of a grasshopper may be retained and used in other metabolic activities?
  1. water
  2. uric acid
  3. carbon dioxide
  4. feces

Correct Answer Number: 1

Explanation: The four metabolic waste products are water, carbon dioxide, salts, and nitrogenous wastes. Water is necessary for many chemical reactions including hydrolysis but it is a waste product of dehydration synthesis occuring in the cells.


Material Cycles: Question 3 of 4
Events that take place in a biome are shown in the diagram below. Which information formation is represented in the diagram?
 

  1. Respiration and photosynthesis are interrelated.
  2. Transpiration and condensation are related to the water cycle.
  3. Decomposers release a material that is acted on by other organisms.
  4. Predators and their prey are involved in many interactions.

Correct Answer Number: 3

Explanation: This diagram illustrates the nitrogen cycle. Different forms of nitrogen must be taken in by certain organisms, changed into other forms and released for other organisms to be able to take it in. Bacteria are a type of decomposer that can convert nitrogen into forms other organisms can use.


Material Cycles: Question 4 of 4
An ecosystem, such as an aquarium, is self-sustaining if it involves the interaction between organisms, a flow of energy, and the presence of
  1. equal numbers of plants and animals
  2. more animals than plants
  3. materials cycles
  4. pioneer organisms

Correct Answer Number: 3

Explanation: If a ecosystem is to be self-sustaining, materials such as oxygen, carbon dioxide, water and nitrogen must be able to recycle between the organisms.
