Question 1

Ecoysystem

Answer 1

a biological community of interacting organisms and their physical environment.

Question 2

Biotic factor

Answer 2

the living components of an ecosystem. They are sorted into three groups: producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores.

Question 3

Abiotic factor

Answer 3

a non-living component in the environment. This can be either a chemical or physical presence.

Question 4

Organism

Answer 4

refers to any individual living thing that can react to stimuli, reproduce, grow, and maintain homeostasis. It can be a virus, bacterium, protist, fungus, plant or an animal

Question 5

species

Answer 5

A group of closely related organisms that are very similar to each other and are usually capable of interbreeding and producing fertile offspring.

Question 6

population

Answer 6

the number of organisms of the same species that live in a particular geographic area at the same time, with the capability of interbreeding.

Question 7

habitat

Answer 7

place where an organism or a community of organisms lives, including all living and nonliving factors or conditions of the surrounding environment.

Question 8

Natural Selection

Answer 8

which, according to Darwin’s theory of evolution, only the organisms best adapted to their environment tend to survive and transmit their genetic characters in increasing numbers to succeeding generations while those less adapted tend to be eliminated.

Question 9

evolution

Answer 9

the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.

Question 10

Producers / autotrophs

Answer 10

An organism capable of synthesizing its own food from inorganic substances using light or chemical energy. Green plants, algae, and certain bacteria are autotrophs.

Question 11

Consumers / heterotrophs

Answer 11

An organism that cannot manufacture its own food and instead obtains its food and energy by taking in organic substances, usually plant or animal matter. All animals, protozoans, fungi, and most bacteria are heterotrophs. Compare autotroph.

Question 12

Primary consumer

Answer 12

Examples of Primary Consumers. We just established that the primary consumer is the living organism that eats the producers, which are the plants.

Question 13

secondary consumer

Answer 13

eat these plants exclusively and are all herbivores. We defined secondary consumers as organisms, primarily animals, which eat primary consumers.

Question 14

Tertiary consumer

Answer 14

Word Origin. noun Ecology. a carnivore at the topmost level in a food chain that feeds on other carnivores; an animal that feeds only on secondary consumers.

Question 15

Herbivores

Answer 15

an animal that feeds on plants.

Question 16

Carnivores

Answer 16

noun, plural: carnivores. An animal or plant (particularly insect- and invertebrate-eating plants) that requires a staple diet consisting mainly or exclusively of animal tissue through predation or scavenging. Supplement.

Question 17

Omnivores

Answer 17

kind of animal that eats either other animals or plants. S

Question 18

Decomposers

Answer 18

organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition.

Question 19

Food chain

Answer 19

a linear network of links in a food web starting from producer organisms (such as grass or trees which use radiation from the Sun to make their food)

Question 20

. Food web

Answer 20

A graphical model showing the interconnecting food chains in an ecological community.

Question 21

Energy pyramid

Answer 21

a graphical model of energy flow in a community. The different levels represent different groups of organisms that might compose a food chain.

Question 22

Carbon cycle

Answer 22

The combined processes, including photosynthesis, decomposition, and respiration, by which carbon as a component of various compounds cycles between its major reservoirs-the atmosphere, oceans, and living organisms. carbon dioxide cycle.

Question 23

. Nitrogen cycle

Answer 23

A nonmetallic element that makes up about 78 percent of the atmosphere by volume, occurring as a colorless, odorless gas. It is a component of all proteins, making it essential for life, and it is also found in various minerals.

Question 24

Ecological succession

Answer 24

A system that includes all living organisms (biotic factors) in an area as well as its physical environment (abiotic factors) functioning together as a unit.

Question 25

Primary succession

Answer 25

Primary succession occurs in essentially lifeless areas—regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier.

Question 26

Secondary succession

Answer 26

a process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem

Question 27

Pioneer species

Answer 27

Pioneer species are hardy species which are the first to colonize previously disrupted or damaged ecosystems, beginning a chain of ecological succession that ultimately leads to a more biodiverse steady-state ecosystem.

Question 28

Climax community

Answer 28

In ecology, climax community, or climatic climax community, is a historic term for a biological community of plants, animals, and fungi which, through the process of ecological succession in the development of vegetation in an area over time, have reached a steady state
