Q

Predator-Prey Cycle

A

When a species population rapidly multiplies, the number for predators increases. As the predator eventually eats all the prey, the prey population decreases and predo population decreased due to starvation

17
Q

Controlled variable/constant

A

an experimental element which is constant (controlled) and unchanged throughout the course of the investigation.

18
Q

Competitive Exclusion Principle

A

two species which compete for the same limited resource cannot coexist at constant population values.

19
Q

Mechanical defense

A

armor in animals or thorns in plants, discourage predation and herbivory by discouraging physical contact

20
Q

Behavioral defense

A

to avoid or confuses predators they play dead or travel in large groups

21
Q

Chemical defense

A

plant species produce secondary plant compounds that serve no function for the plant except that they are toxic to animals and discourage consumption.

22
Q

Physical defense

A

physical appearance, such as body shape and coloration, to avoid being detected by predators. coloration as a way of warning predators that they are distasteful or poisonous. Camouflage

23
Q

Symbiosis

A

a relationship or interaction between two or more species that share a common habitat.

24
Q

Pioneer species

A

species that first colonize new habitats created by disturbance (bacteria, lichen, mosses, and fungi)

25
Q

Commensalism

A

occurs when one species benefits from a close prolonged interaction, while the other neither benefits nor is harmed.

26
Q

Biodiversity

A

The variety of life on Earth including all organisms and ecosystems

27
Q

Resistance

A

Ability to handle changes without losing its basic function

28
Q

Resilience

A

The speed of recovery after disturbances

29
Q

Autotroph

A

is an organism that can convert abiotic sources of energy into energy stored in organic compounds, which can be used by other organisms
ex alge

30
Q

Net primary productivity

A

The amount of energy that plants produce through photosynthesis minus the energy they use for respiration energy available for growth and consumption by herbivores

31
Q

Biomagnification

A

The process where the concentration of toxins increase as a move up the food chain affecting top predators the most

32
Q

Gross primary productivity

A

The total amount of energy produced by plants through photosynthesis before any Organism uses oxygen to release energy from food

33
Q

Nitrogen cycle

A

How nitrogen moves between the atmosphere soil and living things helping plants grow and supporting life

34
Q

Carbon cycle

A

How carbon moves between the atmosphere oceans soil and living things essential for life on Earth

35
Q

Biogeochemical cycle

A

The movement of elements like carbon nitrogen and water through living things in the environment keeping ecosystems balanced

36
Q

CHNOPS

A

Stands for the six key elements in living organisms carbon hydrogen nitrogen oxygen phosphorus and sulfur

37
Q

Phosphorus cycle

A

How philosophers moves through rocks soil water and living things crucial for DNA and energy in cells

38
Q

Sulfur cycle

A

How sulfur moves through rocks soil water and living things in central for proteins and enzymes in organisms

39
Q

Eutrophication

A

The process where water bodies become nutrient-rich leading to excessive algae growth and the blemish harming aquatic life

40
Q

Carbon sink

A

Absorbs and storms more carbon dioxide from the atmosphere then it releases

41
Q

Carbon source

A

Releases more carbon dioxide into the atmosphere than absorbs

42
Q

Carbon store

A

Holds stores carbon
