galaxy group
Smaller groups of 50 or less galaxies held by gravity. our galaxy is in a local group with Andromeda and Triangulum.
galaxy
A concentration of 100 billion (or more) stars, dust, gas and matter held by gravity.
solar system
all of our plants
plant
biosphere
Regions of the Earth’s crust, waters, and atmosphere inhabited by living things
biome

ecosystem
A community plus its non-living (abiotic
community
Interacting populations of different species in a particular area.
population
Several organisms of the same kind (species) in a particular area.
organism
An individual living thing that contains several organ systems.
organ
Composed of a number of tissues and organized for a particular task in a system.
tissue
A group of cells wot a common structure and function
cell
the smallest unit of a living thing
molecule
a non-living substance that makes a cell
atom
the smallest unit of a molecule
ecosystem
contains several habitats, which are placing organism live. contains habitats that are found on land, and habitats that are found in ocean, terrestrial, aquatic habitats
biotic
All living (or once living) components of an ecosystem.
abiotic
All non-living components of an ecosystem.
what is a ecological niche niches
all interactions an organism has with its environment.
ATMOSPHERE
Layer of gases that surround the planet.
LITHOSPHERE
Earth’s solid outer layer.
Sometimes called geosphere.
HYDROSPHERE

First Law
Energy can be changed from one form to another, but cannot be created nor
destroyed.
Second Law
Each time energy is transferred; some energy is lost mainly as heat.
what is the energy form the sun called
solar radiation energy, including uv enegry, and light enegry
what is the main source of photosynthetically
light enegry
what is photosynthetically
is the process in which the sun energy is converted to chemical energy
cellular respiration
is the process in what store chemical energy is released. ( can be used by the organism all organism can carry out this process
carbon compounds
carbon compounds like carbon dioxide or sugar help carry energy throughout an ecosystem
carbon cycle
is a series of processes that moves carbon between the abiotic and biotic parts of the ecosystem
what is carbon
it is an instrumental element in ecosystems
what is chrorophyll
it traps light, stores its energy in sugar, and is what makes plants green
carbon dioxide
is a gas that is present in the atmosphere and is formed when any foul containing carbon is burned
