Unit 5 Flashcards
Niche
What the organism does with its environment
Habitat
Where an organism lives
Biodiversity
The variety of different types of life found on earth. It is a measure of the variety of organisms present in different ecosystems. This can refer to genetic variation, ecosystem variation, or species variation (number of species) within an area, biome, or planet.
Producers
Organisms that make everything
Energy Pyramid
the graphical representation of the trophic levels (nutritional) by which the incoming solar energy is transferred into an ecosystem. The source of energy for living beings on Earth is the Sun.
Ecology
the branch of biology that deals with the relations of organisms to one another and to their physical surroundings.
Consumer
a thing that eats or uses something.
Abiotic
physical rather than biological; not derived from living organisms.
Ecosystem
a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system.
Biotic
of, relating to, or resulting from living things, especially in their ecological relations.
Food chain
a hierarchical series of organisms each dependent on the next as a source of food.
Food web
a system of interlocking and interdependent food chains.
Organism
an individual animal, plant, or single-celled life form.
synonyms:
Decomposer
organisms that break down dead or decaying organisms, and in doing so, carry out the natural process of decomposition. Like herbivores and predators, decomposers are heterotrophic, meaning that they use organic substrates to get their energy, carbon and nutrients for growth and development.
Herbivore
Plant eater
Carnivore
Meat eaters
Omnivore
Meat and plant eaters
Scientific method
a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. To be termed scientific, a method of inquiry is commonly based on empirical or measurable evidence subject to specific principles of reasoning.
Observation
the action or process of observing something or someone carefully or in order to gain information.
Expirimental group
The group that gets the special stuff that u test
Control group
The group that stays the same
Theory
a contemplative and rational type of abstract or generalizing thinking, or the results of such thinking. Depending on the context, the results might for example include generalized explanations of how nature works. Wikipedia
Hypothesis
What u think will happen with the expiriment
Prediction
What u think the expirimental group will do
Independant variable
The thing that changes in the expiriment
Expiriment
The thing u do when u want to test a prediction or hypothesis
Developement
When an organism changes it way of life
Organization
How u put things into groups
Evolution
How a species changes over time
Adaptation
How an individual changes over time to its environment
Natural selection
the differential survival and reproduction (i.e., fitness) of individuals that differ in phenotype. It is a key mechanism of evolution.
Reproduction
When 2 or 1 individuals make an offspring
