Describe characteristics of these biomes Tundra Forest: Tundra biome-no trees, below freezing, permafrost

Forest-warm, wet weather, lush plant growth wtih weight loss
Differences between descriptive or qualitative data and quantitative data?: Descriptive data tells characteristics of something
and is qualitative.

Quantitative data uses numerical data to validate something
Differences between control group and experimental group: Control group- no changes are made
Experimental group-variables are changed to effect a result
Differences between a pioneer community, climax community: Pioneer community-first to colonize an area

Climax community-stable or mature community with little change
Differences between primary succession and secondary succession: Primary succession-beginning of organisms on land that is barren and organisms eventually die out

Secondary succession-sequence of changes that happen after an existing community is severely disrupted in some way
Where are coniferous forests found?: Coniferous forests are found in the tiaga just south of the tundra
Differences between aphotic zone and photic zone of the tidal area of the ocean: aphotic-no light deeper zone
photic-light higher zone
Define succession: Succession is defined as orderly, natural replacement of communities in the ecosystems
Define intertidal zone: Intertidal zone is the portion of the shoreline that lies between the high and low tide lines
What is humus? What is permafrost: Humas is a layer of soil that is made up of partially decomposed organisms

Permafrost is a layer of soil that remains frozen year round
stimulus and response: Stimulus is what causes a reaction or response

Response is a reaction to a stimulus
The way that living things change during their lives is often called: growth and development
Reproduction: The making of living things from living things
Parts of a scientific experimentation and their definitions: Observations-looking at the world around you
Problem-question about something occurring
Hypothesis-educated guess to answer of problem and can be tested
Experimentation-addition/subtraction of variables to test the hypothesis
Dependent variables-changes that depend on independent variable factors affecting the outcome of the experiment
Data-numerical measurements of experiment results are quantitative
Observable differences are qualitative or descriptive
Results-findings learned from data
Differences of abiotic and biotic characteristics: abiotic-without life
biotic-living
Transpiration Photosynthesis Infiltration Precipitation: Transpiration-loss of water to biosphere
Photosynthesis-process of plants making food
Infiltration-to bring into a group
Precipitation-form of water to earth from atmosphere
How is nitrogen released into the biosphere?: Nitrogen is released through death and decay of organisms
How does carbon dioxide enter the living parts of the biosphere?: Carbon dioxide enters the biotic parts of biosphere through the photosynthesis of plants
Define mutualism parasitism commensalism symbiosis: Mutualism-both parties benefit
Parasitism-one party lives off another causing harm to it.
Commensulism-symbiotic relationship in which one species lives off another and neither is harmed
Symbiosis-close and permanent relationship between organisms of different species
Define habitat community niche: habitat-place where organism lives

community-interacting organisms living together

niche-strategies and adaptations used to live in environment
Define population ecosystem biological community: population-group of organisms all of the same species

ecosystem-interacting populations in a biological community and the abiotic factors

biological community-interacting populations in a certain area at a certain time
Differences between a heterotroph and an autotroph?: heterotroph-cannot make its own food and feeds off other organisms

autotroph-organism that uses light energy to make own food
Producer Consumer Decomposer: Producer-makes food

Consumer-eats food

Decomposer-break down complex compounds of dead and decaying plants and animals into smaller molecules
food chain: Food chain-model used to show how matter and energy moves through ecosystem
Food web: Food web-shows all possible feeding relationships at each tropic level in a community
Trophic level: Trophic level-a feeding step in the food chain in the passage of energy and materials
Autotroph 1st order heterotroph 2nd order heterotroph 3rd order heterotroph: Autotroph-producers such as grasses, trees, etc
1st order heterotroph-herbivores who eat plants-deer, turtles,etc
2nd order heterotroph-carnivores who eat small animals-feed off of other animals, owls, fish, birds, etc
3rd order heterotroph-large animals who feed off of smaller animals: bears, cougars, etc
Amount of energy lost in the food chain: For 10,000 units of energy, 9990 units are lost by the time it travels through the food chain
As energy moves through the food chain, the amount of available energy is: decreased
Bacteria reproduce rapidly or slowly?: Bacteria reproduce rapidly
Population that grows until it reaches it carrying capacity has what letter shape?: It has the shape of the letter S
Differences between density dependent and density independent: density dependent -include disease, competition, predators, parasites and food

density independent-include abiotic factors such as volcanic eruptions, temperature, storms, floods, drought, chemical pesticides, and major habitat disruption
Define carrying capacity: Carrying capacity-the number of organisms an environment can support
