q. Food Chain
A series of steps in which organisms transfer energy by eating and being eaten
r. Food Web
Links all food chains in an ecosystem together
S. Biomass
A measure of the total dry mass of organisms (living tissue) within a trophic level in an ecosystem
t. Primary Productivity
Rate at which producers in an ecosystem build biomass
u. Ecological Pyramid
Pyramid shaped diagrams that show the amount of energy or matter at each trophic level in an ecosystem. There are 3 types, energy pyramid, biomass pyramid, and pyramid of numbers
v. Transpiration
Evaporation of water from the leaves of a plant
w. Greenhouse Effect
The process by which certain gases (principally water vapor, carbon dioxide, and methane) trap heat that would otherwise escape the earth and radiate into space
x. Symbiosis
A close relationship between two or more species where at least one benefits
y. Habitat
The specific environment of an organism both biotic and abiotic
z. Niche
An organism’s role in its ecosystem, including its habitat, physical requirements (light, water, food sources), the time of day it is active, its place on the food chain, and when and how it reproduces
aa. Mutualism
A symbiotic relationship between two or more organisms of different species where all benefit from the association
