Unit A 1.0-2.0 Flashcards
What is Biological Diversity?
Difference/variety of living organisms on earth.
All living things are…
Hint: 5 things
GRACED Growth Reproduce Adaptations Cells Develope
What is ecological diversity? Give examples.
Variety between ecosystems.
Ex. Different species, organisms, landscape, etc.
What is species diversity? Give examples.
Variety between species.
Ex. Fur vs. Scales, size, colour, diet, etc.
What is genetic diversity? Give examples.
Variety within a species.
Ex. Blood type, DNA and cell structure, etc.
What is an ecosystem?
Biotic things interact with other biotic and abiotic things in a shared environment.
Define biotic.
Alive or once-living.
Define abiotic.
Non-living.
What is an individual?
Its own organism; nothing “smaller”.
What is a species?
A group of LIVING organisms that are all very similar and can successfully reproduce.
What is a population?
A group of the same species that all live together and use the same resources.
What is a community?
When multiple populations live in the same area and share an environment.
What is the order of the big-small scale?
Individual —> species —> population —> community —> ecosystem.
Where in the world has the most diversity?
The equator and surrounding areas.
Where has the least diversity?
Farther from the equator.
Why is there more diversity closer to the equator?
Because the sun’s rays are more concentrated there because its flatter.
Who created the system for classifying organisms?
Carolus Linnaeus.
Whats the name of the system for classifying organisms?
Binomial Nomenclature.
What language is the classifying system based off of?
Latin.
How many words does the classifying system use?
2.
What are the 2 words for the classifying system?
Genus and species.
Define genus.
- first word.
- what… kind, or type, of organism.
- CANIS Rufus
Define species (classifying version).
- second word.
- what species the organism is.
- Canis RUFUS
What’s interdependence?
The dependence of 2 or more species on each other.
Name 2 things plants provide, and give an example for each.
- Oxygen
Trees absorb the CO2 we excrete, and give us back oxygen that we use to breath.
Give an example of a food chain.
Choose one. It’s just the energy transfer between things. Write it down if that helps.
What’s symbiosis?
An association between members of different species.
What are the 3 types of symbiosis?
Commensalism, mutualism, parasitism.
What is commensalism? Give an example.
One benefits, other unaffected.
+/0
Ex. Barnacles on a whale.
What is mutualism? Give an example.
Both benefit.
+/+
Ex. Bee and flower.
What is parasitism? Give an example.
One benefits, the other is harmed.
+/-
Ex. Tapeworm and human.
What 2 words does the word symbiosis come from? Give meanings.
Sym = together Bio = alive
What is interspecies competition?
When different species compete for the same resource or niche.
What is a niche?
How an organism interacts with its environment and what conditions are best suited to it.
Ex. What it eats, what eats it, where it sleeps, etc.
What is a human’s niche?
My house, my food, etc.
What is resource partitioning?
When species change their niche slightly to incorporate other species to avoid competition.
