Cells
Name a difference between plant and animal cells.
Plant cells have cell walls, one large vacuole, and chloroplasts.
Body's reaction to overheating.
It begins to sweat.
Cell structure where photosynthesis occurs.
chloroplasts
How much energy is USED by consumers at each trophic level?
90%
What is a biome?
A group of ecosystems that share similar climates and typical organisms.
Known as the "powerhouse of the cell"
Mitochondrion
Body's reaction to getting too cold.
Begins to shiver.
chlorophyll
How much energy is PASSED from one trophic level to the next?
10%
Which biome covers approximately 70% of the Earth's surface?
Marine/Ocean biome
Levels of cellular organization in order from least to most complex.
cell->tissue->organ->organ system->organism
A body's response to stimuli that occur automatically. (sweating/shivering)
Involuntary responses
3 things needed for plants to undergo photosynthesis.
carbon dioxide, water, sunlight
Give an example of a food chain with 2 consumers.
Producer (grass) ->primary consumer (rabbit) ->secondary consumer (coyote)
A biome that is extremely hot and dry, with little water and few plants.
Desert
Tiny structures that perform specific jobs inside of a cell; a cell organ.
organelle(s)
Occurs when an organism is experiencing a lack of water intake.
dehydration
What type of energy conversion happens during photosynthesis?
Light energy -> Chemical energy
What is a food chain?
A SINGLE PATH in which organisms transfer energy by eating and being eaten.
A biome with 4 season, plants that shed leaves in the fall and grow new ones in the spring.
Deciduous forest
This is a structure where proteins are synthesized.
ribosomes
What is homeostasis?
An organism's ability to maintain stable internal conditions in a changing environment.
What are the TWO products of photosynthesis?
Glucose and Oxygen
What is a food web?
A system of interlocking and independent food chains. (MANY PATHS)
A cone bearing tree that usually keeps its leaves or needles during all seasons of the year.
Coniferous trees
