BadFish Quizizz Eco 1: Producers/Consumers/Decomposers/Cycles

There are many types of biotic objecs in an ecosystem - producers, consumers, decomposer, autotrophs and heterotrophs. What of the following type of organism makes its own food?

• consumesr aka autotrophs

• carnivores aka producers

• producers aka autotrophs

• animals aka Kingdom Animalia

All organisms are connected in the ecosystem. From where do autotrophs get their energy?

• the ground
• other animals
• decomposers
• the sun

There are organisms that make up the FBI (fungi, bacteria and invertebrates—worms and insects). They are all living things that get energy by eating dead animals and plants and breaking down wastes of other animals. Which of the following are consumers that get their energy by breaking down dead organisms, thus sending nutrients into the soil?

• scavengers

• carrion

• decomposers

• animals

Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle. The ocean also plays a critical role in carbon storage, as it holds about 50 times more carbon than the atmosphere. There are autotrophs on land and sea. What is the function of those autotrophs in the carbon cycle?

• To use carbon dioxide to make organic compounds like glucose

• To take in excess water

• To feed herbivores

• To use oxygen to produce glucose, one of the four major macromolecules that makes up all living things

Decomposers are the organisms that break down decaying organisms. They are connected to all other organisms in the cycle of life. What is the role of decomposers in the carbon and nitrogen cycles?

• They release carbon and nitrogen stored in organisms by breaking them down

• They take carbon and nitrogen out of the atmosphere through photosynthesis

• They create oxygen compounds that can be used by plants

• They store carbon and nitrogen

If elements are to be recycled in nature, which organisms must be present?

• Producers, Consumers and Decomposers

• Herbivores and Carnivores and Decomposers

• Parasites and Bacteria

• Predators and Prey

The species that make up an ecosystem are connected in complex “food webs” of eater and eaten. When one species disappears, its predators can no longer eat it and its prey are no longer eaten by it. Changes in these populations affect others. Such impact ‘cascades’ (passed on) can be unpredictable and sometimes catastrophic. The removal of which of the following types of organisms would have the greatest negative effect on an ecosystem?

• Apex predators

• Heterotrophs

• Autotrophs

• Decomposers

An increase in carbon dioxide levels could be one of the reasons why you feel drowsy, have throbbing headaches, or struggle to be as productive. Though the odorless gas is safe in minor amounts, the levels can go up when there is reduced ventilation, especially in our homes or offices. There many ways to reduce CO2 in our atmosphere at home and in nature. What process takes CO2 out of the atmosphere?

• Nitrogen fixation

• Cellular respiration

• Transpiration

• Photosynthesis

What is an organism called that produces its own food supply from inorganic compounds (glucose) ?

• heterotroph
• consumer
• detritivore
• autotroph

Living things have to hunt, gather and eat their food in order to survive. Which of the following is an organism that needs to eat other organisms to obtain energy?

• Autotroph
• Producer
• Consumer
• Mutualist
