Biomass

1 / 34

35 Terms

1

Biomass

The total mass/weight of all the living organisms in a given population/area

New cards
2

Conservation of Matter

In any chemical reaction, matter changes form; it's neither created nor destroyed

New cards
3

Carbon sinks

Places of carbon accumulation, such as in large forests (organic compounds) or ocean sediments (calcium carbonate); carbon is thus removed from the carbon cycle for moderately long to very long periods of time

New cards
4

Cells

Minute biological compartments within which the processes of life are carried out

New cards
5

Carnivores

Organisms that prey mainly upon animals

New cards
6

Chemical energy

Potential energy stored in chemical bonds of molecules

New cards
7

Compound

A molecule made up of two or more kinds of atoms held together by chemical bonds

New cards
8

Cellular respiration

The process in which a cell breaks down sugar or other organic compounds to release energy used for cellular work; may be anaerobic/aerobic, depending on the availability of oxygen

New cards
9

Consumers

Organisms that obtain energy and nutrients by feeding on other organisms or their remains

New cards
10

Decomposers

Fungi and bacteria that down complex organic material into smaller molecules

New cards
11

Detrivores

Organisms that organic litter, debris, and dung

New cards
12

Ecology

The scientific study of relationships between organisms and their environment. It is concerned with the life histories, distribution, and behavior of individual species as well as the structure and function of natural systems at the level of populations, communities, and ecosystems.

New cards
13

Ecosystems

A specific biological community and its physical environment interacting in an exchange of matter and energy

New cards
14

Energy

The capacity to do work (to change the physical state or motion of an object)

New cards
15

Enzymes

Molecules, usually proteins or nucleic acids, that act as catalysts in biochemical reactions

New cards
16

First law of thermodynamics

energy can not be created nor destroyed, only converted

New cards
17

Food chain

A linked feeding series, in an ecosystem, the sequence of organisms through which energy and materials are transferred, in the form of food, from one trophic level to another

New cards
18

Food web

A complex, interlocking series of individual food chains in an ecosystem

New cards
19

Heat

A form of energy transferred from one body to another because of a difference in temperatures

New cards
20

Herbivores

Organisms that only eat plants

New cards
21

Ions

Electrically charged atoms that have gained/lost electrons

New cards
22

Isotopes

Forms of a single element that differ in atomic mass due to having a different number of neutrons in the nucleus

New cards
23

Kinetic energy

Energy contained in moving objects, such as a rock rolling down a hill, the wind blowing through the trees, or water flowing over a dam

New cards
24

Matter

Anything that takes up space and has mass

New cards
25

Metabolism

All the energy and matter exchanges that occur within a cell or organism; collectively, the life processes

New cards
26

Molecules

Combinations of two or more atoms

New cards
27

Omnivores

Organisms that eat plants and animals

New cards
28

Photosynthesis

The biochemical process by which green plants and some bacteria capture light energy and use it to produce chemical bonds.. Carbon oxide and water are consumed while oxygen and simple sugars are produced

New cards
29

Population

A group of individuals of the same species occupying a given area

New cards
30

Producers

Organisms that synthesizes food molecules from inorganic compounds by using an external source; most producers are photosynthetic

New cards
31

Productivity

Synthesis of new organic material; synthesis done by green plants using solar energy is called primary productivity

New cards
32

Scavengers

Organisms that feed on dead bodies of other organisms

New cards
33

Species

Populations of morphologically similar organisms that can reproduce sexually among themselves but that cannot produce fertile offspring when mated with other organisms

New cards
34

Temperature

A measure of the speed of motion of a typical atom or molecule in a substance

New cards
35

Trophic Level

A step in the movement energy through an ecosystem; an organism's feeding status in an ecosystem
