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
|
