Biology Quiz Review

The scientific study of interactions between different organisms and between organisms and their environment or surrounding.

• Biology

• Symbiosis

• Ecology

• Qualitative Observation

Answer explanation

Biology is the study of all living things. The question talks about organisms interacting with their environment.

Symbiosis is specifically species to species. The definition also include the abiotic factors, the environment.

Qualitative Observation is simply researching an organism attributes.

Vocab: Living factors that influence an ecosystem.

• Biotic

• Organism

• Competition

• Natural Selection

Answer explanation

In a way, all of the answer choices are correct, so I put the vocab tag thingy.

Organisms are any life form and the definition includes that it influences the ecosystem. Some type of living factors like a stick aren't considered organisms.

Competition is two organisms trying to use the same natural resources. In some way this answer is correct but the competition is much more related to species to species. The definition is looking for interaction between species and environment.

Natural Selection is Darwin's theory of evolution. The definition says nothing about evolution. Don't pick it.

Vocab: Non-living factors that influence an ecosystem

• Decomposers

• Abiotic

• Temperature

• Atoms

Answer explanation

Decomposers are still living factors.

Temperature is one of the many factors. Temperature is factor but it doesn't meet the criteria of Factor's'.

Atoms are the building blocks of all things. The question is matching definitions to a term.

What is the main energy source for life on Earth?

Answer explanation

The Sun is what gives plants energy which eventually fuels all organisms above them. The Sun also plays a major role in our climate.

What type of organisms produce their own food?

• Autotrophs

• Heterotrophs

• Abiotic Factors

• Chloroplast

Answer explanation

Heterotrophs are organisms that rely on consuming other organisms to receive energy.

Abiotic factors are non-living things, so they don't need energy or food to survive.

Chloroplast have a role in creating food but they aren't organisms.

What process, which only occurs in autotrophs, requires light energy, CO2 to convert it to O2 and C6H12O6)

Answer explanation

It is the process of photosynthesis.

Vocab: A process performed by bacteria, uses chemical energy to produce carbohydrates.

• Carbohydrate synthesis

• Chemosynthesis

• Photosynthesis

• Chemical Translation

Answer explanation

Carbohydrate synthesis and chemical translations are made up terms. Try to remove terms you've never seen.

Photosynthesis occurs in all autotrophs. It isn't just limited to bacteria.

Organisms that rely on other organisms for their energy and food supply.

• Carnivores

• Heterotrophs

• Autotrophs

• Predation

Answer explanation

Carnivores specifically eat other animals. The definition simply talks about eating organisms.

Autotrophs make their own food.

Predation is specifically eating another animal. The definition simply talks about eating organisms.

An organism that only eats plants

Answer explanation

Herbivores eat plants. .-.

An organism that eats both plants and animals

Answer explanation

Omnivores do in fact eat both plants and animals.
