Body systems
what is the system that maintains homeostasis, and produces hormones?
Endocrine
what is the definition of classification?
The naming and organization of organisms
What is the area of land called where all the water drains to the same place, such as a river or lake?
A watershed.
This organism is the base of the food web and can make it's own food.
Producers.
Definition of Artificial and Natural selection
Bonus: Give me an example of Natural and Artificial selection
Artificial: The process by which humans breed only the traits they find useful.
Natural: A process by which individuals better suited to their environment survive and reproduce more than others.
how do the skeletal and muscular system work together?
The skeletal and muscular systems work together to move the body.
What is the meaning of multi and uni cellular?
Multicellular: An organism made up of multiple cells
Unicellular: An organism with only one cell
Name one way that humans can help protect watersheds from pollution.
What is planting trees, using less fertilizer, picking up pet waste, or reducing litter?
How much energy is transferred up throughout the energy pyramid.
Bonus: What happens to the percent that is not transferred.
10% is transferred from one or organism to another.
What process of reproduction provides the genetic diversity necessary for natural and artificial selection?
Sexual reproduction.
what are the 3 main structures of the circulatory system?
The heart, Blood vessels, Blood
what are the 7 classifications?
Domain, Kingdom, phylum, class, order, family, species
Why does pollution in a small stream affect larger bodies of water like rivers, lakes, and even oceans?
Because all water in a watershed is connected and flows downstream.
A food chain is a single line of organisms.
(Ex: Grass -> Rabbit -> Fox -> Wolf)
A food web is a combination of several food chains.
How do people choose what species to breed?
They choose by thinking about there wants and needs.
what are the main 3 structures of the muscular system? what do they do?
Cardiac: responsible for pumping blood
skeletal: attaches to the bones and produces movement
smooth: moves nutrients and waste through the body
what is the meaning of Heterotrophic and Autotrophic?
Bonus: give me an example of both
Heterotrophic: Organisms that eat other organisms for energy
Autotrophic: organisms that make their own food
Name one common pollutant found in water runoff from farms.
What is fertilizer, pesticide, or animal waste?
Provide an example of a decomposer and explain how they aid in energy transfer in an ecosystem.
Fungi, bacteria, worms, etc.
Decomposers break down organic matter and return the nutrients to the soil for producers to grow.
Would selective breeding be useful to the environment beside human wanting, and why?
typically no because selective breeding is made for human desire not for environment base.
what is the main function of the immune system?
Attacks pathogens once they enter the body.
What is the definition of prokaryotic and Eukaryotic?
Bonus: how do we remember these
Prokaryotic: A cell without a nucleus
Eukaryotic: A cell with a nucleus
Bonus-Pro=No
Eu=Nu
What human activity, known for releasing greenhouse gases, is a major contributor to the warming of ocean temperatures
Industrial activity
Name an organism that is heterotrophic, multicellular, and a secondary consumer.
Any organism that eats a primary consumer is a secondary consumer.
Charles Darwin placed the same species of bird on four different islands with different sources of food. What happened to the birds after some time has passed? Is would this be considered natural selection or artificial selection.
The developed different traits based on the island they were on. This is a result of natural selection, the best traits were passed down from parent to offspring.
