6.L.2 Ecosystems Vocab

Front

Non-living component of an ecosystem affecting organisms

Back

Abiotic Factor

Answer explanation

The correct option is 'Abiotic Factor'. This refers to the non-living parts of an ecosystem, like sunlight, temperature, or soil, that can impact the organisms living there.

Front

Ecosystem contained in water (fresh/salt)

Back

Aquatic Ecosystem

Answer explanation

An ecosystem that exists within a body of water is referred to as an Aquatic Ecosystem. This can be either freshwater (like lakes and rivers) or saltwater (such as seas and oceans).

Front

Living component of an ecosystem affecting an organism

Back

Biotic Factor

Answer explanation

Biotic factors include any living organism, like plants, animals, fungi, bacteria, etc. The other options: 'Biology', 'Food Web', and 'Decomposer' are not specific living components of an ecosystem.

Front

Organism that cannot make its own food and gets energy from others.

Back

Consumer

Answer explanation

Consumers, unlike producers, cannot photosynthesize or make their own food and rely on "eating" other organisms for energy.

Front

Organism that derives nutrients from breaking down dead matter.

Back

Decomposer

Answer explanation

Decomposers, like bacteria and fungi, are organisms that break down dead or decaying organisms. They carry out the natural process of decomposition and add nutrients back to the environment again.

Front

Community of organisms in a physical environment

Back

Ecosystem

Front

Linear series of organisms feeding off lower levels

Back

Food Chain

Answer explanation

A food chain is a linear sequence of organisms where each organism is eaten by the next one in the chain, thus feeding off lower levels. Both producers and consumers can be a part of a food chain but don't fit this definition

Front

Complex system of organisms supplying energy to multiple levels

Back

Food Web

Answer explanation

The question describes a complex system of organisms that interact at multiple levels, not just one level as in a food chain. This is characteristic of a 'Food Web', where multiple organisms at different levels interact, feed off, or supply energy to each other. Therefore, the correct answer is 'Food Web'.

Front

Organism that makes its own food from abiotic sources (autotroph)

Back

Producer

Answer explanation

The question asks about an organism that can create its own food from non-living sources, which is characteristic of autotrophs. Producers, such as plants, can produce their own food through photosynthesis.

Front

Reaction or reflex due to an outside factor

Back

Response

Answer explanation

A response is a reaction or change in behavior that occurs when something in the organism's environment changes.
