This set of Energy & Environment Management Multiple Choice Questions & Answers (MCQs) focuses on “Producers”.
1. Consumer for food that feeds on producers are known as_____________________
a) Carnivores
b) Consumers
c) Herbivores
d) Producers
View Answer
Explanation: Animals that eat only plants are called as herbivores. Plants are called producers because they are able to use light energy from the sun to produce food from carbon dioxide and water. Herbivores are also known as primary consumers.
2. The food chain from grass to hawk and again it comes back to grass with the help of fungi. In the above explain food chain, what is grass?
a) Producers
b) Consumers
c) Decomposers
d) Energy source
View Answer
Explanation: Green is a producer. It is a self sustaining organism that obtains its energy directly from sun. In the process, grass introduces few new organic substances into the food chain and grass plays a key role for consumers.
3. The process in which green plants and few organisms use sunlight to synthesize nutrients is known_________________
a) Chemosynthesis
b) Photosynthesis
c) Food chain
d) Food web
View Answer
Explanation: Photoautotroph’s are the organisms involves in photosynthesis. It uses energy from sun to convert water from the soil and carbon dioxide from the air into glucose. Glucose provides energy to plants and is used to make cellulose which is used to build cell walls.
4. The process of making food by certain microbes create energy by some chemical reactions is known as_______________________
a) Photosynthesis
b) Food chain
c) Chemosynthesis
d) Hetrosynthesis
View Answer
Explanation: Chemoautotrophy is the organism which produces chemosynthesis. It uses energy from chemical reactions to make food. The chemical reactions are usually between methane with oxygen. Carbon dioxide is the main source of carbon for chemoautotrophy.
5. The grass is a produces.
a) True
b) False
View Answer
Explanation: Grass is a producer because it generates its own food and gets energy from the sun. Grass photosynthesizes and acts as food to other animals. It is also produced and takes in carbon dioxide by releasing oxygen.
6. The food chain level in autotrophy is_____________
a) Primary
b) Secondary
c) Tertiary
d) Quaternary
View Answer
Explanation: All food chains start with autotrophy which is a producer. Autotrophs are eaten by herbivores, organisms that consume plants. Herbivores are the second tropic level. Carnivores and omnivores are secondary consumers.
7. Autotrophic bacteria that produce food through chemosynthesis have also been found at places on the seafloor called_____________________
a) Cold seeps
b) Hot seeps
c) Coral seeps
d) Warm seeps
View Answer
Explanation: A cold seep also called as cold vent. It is an area of the ocean floor where hydrogen sulfide, methane and other liquids leak out of the earth’s crust in the form of brine pool. Cold seeps form a biome which supporting several native species.
8. Most types of algae are classified as producers.
a) True
b) False
View Answer
Explanation: Most of the algae are classified as producers within an ecosystem because they are able to produce their own food. Any plant or organism that can produce its own food through inorganic compounds is known as producers.
9. What makes plant producers?
a) Plants produce their own food
b) Plants depend on other organisms for food
c) Plants are decomposers
d) Plants do not require any energy
View Answer
Explanation: Plants produce their own food. They do this by using light energy from the sun, carbon dioxide from the air and water from the soil to produce food in the form of glucose. The overall process is called as photosynthesis.
10. The producers within an underwater ecosystem are called as_____________________
a) Phytoplankton
b) Autoplankton
c) Hectoplankton
d) Semiplankton
View Answer
Explanation: Phytoplankton is like any other type of plant who changes the sun’s energy into food and they also provide oxygen to their fish friends. Along with phytoplankton seaweed and kelp are also ocean producers.
