Week 1 Flashcards
What is the smallest unit that is fully alive? (I.e. can perform the functions of life)
Cell
What is a biome?
A large ecosystem
Mutualism
Both species benefit from the interactions
Commensalism
One species benefits while the other is seemingly unaffected
What does the term “Niches” mean
Species allow to live side by side & use slightly different resources or obtain it from similar spots/different times
Keystone species
A species that “holds it up”
What does the prefix “eco” mean
House
What does the prefix “enviro”
To surround
Organismic ecologists
Learns everything abt a particular kind of organism
Population ecologists
Study population numbers, distributions, & how & why populations fluctuate overtime
Community ecologist
Study how different species interact
Ecosystem-focused ecologists
Study abiotic factors more than living things
Landscape ecologists
Focus on large-scale patterns
Interspecies competition
Members of two or more different species require the same resource
Intraspecific
interactions among members of the same species
Name levels , smallest to biggest
Atom, molecule, macromolecule, virus, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem, biome, biosphere
Tell me about viruses
They are small, consist of proteins & lipids, and are not alive & cannot replicate
Tell me about molecules
All cell parts are made of molecules
Molecules are made of atoms
Biomes
Huge ecosystem
What is the smallest unit of life
A cell
Community
All living organisms of different species interact
Population
One species living in one place or interacting to reproduce
Organism
One entity
Scientific law
Describe what happens
Scientific theory
Explains why or how it happens
Lets say something is growing on a tree but its not hurting it what is it called
Commensal
In biology the word METABOLIC or METABOLISM refers to..
Any and all of the chemical reactions in a cell/organism
