Nutrition & Energy
the study of interactions among organisms and between organisms and their environment
what is ecology
the flow of energy in an ecosystem flows from _________ to _________
what is sun to autotrophs / producer to consumer / predator to prey
an organism's specific role in its habitat
what is niche
nitrogen is released to the abiotic parts of the biosphere from
what is death and decay by bacteria
the ability of living things to survive the changes in their environment
what is tolerance
organisms that use sunlight or energy stored in chemical compounds to make food
what are autotrophs (or producers)
percent of energy lost at each trophic level of a food chain
what is 10%
water lost to the abiotic (nonliving) parts of the biosphere from biotic parts by the process of
what is transpiration
algae and plants use the abiotic factors of sunlight, carbon dioxide, and water carry out
what is photosynthesis
a stable community formed after a succession
climax community
organisms that rely on other organisms for energy and food
what are heterotrophs (or consumers)
shows how matter and energy move through the ecosystem in a series of steps which organisms transfer energy by eating and being eaten
what is food chain
in this symbiosis both species benefit from the relationship example: rhino & tick bird
in this symbiosis one organism lives on or in an organism and harms it example: dog & tick
tree and moss is an example of this symbiosis
what is mutualism
what is parasitism
what is commensalism
Name the 4 cycles in nature CHNOPs
what is water, carbon, nitrogen, phosphorus
anything that limits an organism's ability to live in a particular environment is a
what is limiting factor
What is the main energy source for almost all ecosystems on earth?
What is the sun
Why are food chains generally limited to 3 or 4 levels
what is lose of energy
several species in an area interact is interested in the biological organization called
what is community
this is the main reservoir of nitrogen
what is atmosphere
a process of gradual, natural change and species replacement that takes place in a community of an ecosystem over time
what is succession
heterotroph that eats.....
only plants
only animals
both
dead remains
what are.....
herbivores
carnivores
omnivores
decomposers
this model shows all possible feeding relationships at each trophic level in a community and links food chains
what is food web
organisms that seek out and eat other organisms
organisms that are eaten
what is predators
what is prey
what do producers release as a result of photosynthesis
what is oxygen
first species of a primary succession
what is pioneer species
the 3 symbiotic relationships MCP
what is mutualism, commensalism, parasitism
elements, compounds, and other forms of matter are passed from one organism to another and from one part of the biosphere to another.
they connect biological, geological and chemical aspects
what is biogeochemical cycles
years of changes that occur after a disturbance in an EXISTING ecosystem
what is secondary succession
strategies and adaptations a species uses in its environment (niche)
what is food, shelter, and reproduces
type of food an organism eats
how it obtains food and shelter
when and how a species reproduces & survives
4 main processes that move carbon in the carbon cycle
1. what is biological processes - photosynthesis, respiration and decomposition 2. geochemical process - erosion and volcanic activity 3. burial and decomposition of dead organisms convert to fossil fuel, 4. mining, cutting and burning forests, burning fossil fuels
Name, describe and give an example of the 2 types of succession
what is primary EX: volcano

and secondary EX: hurricane
