Extinct Extirpated Threatened Endangered( Extinct, Extirpated, Threatened, Endangered )- A species that has died, and no longer remains on Earth
-A species that no longer exists in a certain area is a species that is likely to become if factors reducing it's survival are not changed - : a species facing imminent
CELLULAR RESPIRATION EQUATION ❌ + ❌ > ❌ + water + energy
Label The Hydrologic Cycle
The Carbon Cycle includes Cellular Respiration and Photosynthesis
Ecosystem- all living organisms and their chemical and physical
How can humans restore biodiversity?
Plant trees
Pick up garbage
walk instead of driving
hunting
A representation of the feeding relationships within a community
Food Web
Food Chain
A sequence of organisms, each feeding on the next, showing how energy is transferred from one organism to another
The process in which the Sun's energy is converted into chemical energy is called cellular respiration
Biodiversity: a number of different types of in an area
the level of an organism in an ecosystem depending on it's feeding position along a food chain
Carrying capacity
Trophic level
Ecological Niche
Sustainability
the maximum population size of a particular species that a given ecosystem can sustain
sustainability
ecological niche
carrying capacity
Sustainability: The ability to maintain
: The function a species serves within an ecosystem, Including what it eats, and what eats it as well as behaviour
In Open Ecosystems , things ❌ leave and enter and in Closed Ecosystems things ❌ leave or enter
Int❌specific- Competition between same species ex. bear vs. bear
Int❌specific - competition between different species ex. bear vs. wolf
The Sun is made up of
Hydrogen (25%) and Helium (75%)
Hydrogen (75%) and Helium (25%)
Fire and Heat
Why can we see non-luminous objects?
They give off light
Due to light reflected by the Sun.
The spinning of an object on it's axis
Rotation
Revolution
The movement of the Earth around the Sun.
: occurs every 29.5 days when the unilluminated side of the moon is facing Earth (so it is not visible)
: The name for the second full moon to occur in a month, (this only occurs every 2.7 years)
Occurs when the shadow if the moon falls on the Earth. The Earth passes through the moon's shadow.
Lunar Eclipse
Solar Eclipse
Occurs when the moon passes through the Earth's shadow.
❌ : a grouping of stars as observed from Earth
