Ecology |
the study of the interactions of living organisms with one another and with their environment |
|
Organism |
a living thing; anything that can carry out life process independently |
|
Habitat |
a place where an organism lives and provides the organism with its needs/resources |
|
population |
a group of organisms of the same species that live in a specific geographical area |
|
biology |
the study of life |
|
community |
all of the populations of species that live in the same habitat and interact with each other |
|
food web |
a diagram that shows the complex feeding relationships between organisms in an ecosystem; shows overlapping food chains |
|
ecosystem |
a community of organisms and their abiotic, or nonliving, environment |
|
biosphere |
the part of Earth where life exists |
|
biotic |
describes living factors in the environment |
|
abiotic factor |
describes the nonliving part of the environment, including water, rocks, light, and temperature |
|
species |
a group of organisms that are closely related and can mate to produce fertile offspring |
|
abiotic |
Soil, rocks, climate, water, gases, & sunlight are ___________ factors. |
|
biotic |
Plants, animals, fungi, bacteria, & protists are ____________ factors. |
|
producer |
A p___________ is an organism that can make its own food by using energy from it’s surroundings. |
|
autotroph |
An a_____________ is an organism that can make its own food by using energy from it’s surroundings. |
|
consumer |
A c_____________ is an organism that eats other organisms or organic matter. |
|
heterotroph |
A h_____________ is an organism that eats other organisms or organic matter. |
|
Food chain |
shows the pathway of energy transferred from one organism to the next |
|
Energy pyramid |
a triangular diagram that shows how much energy istransferred between feeding levels in a food web; shows an ecosystem's loss ofenergy, which results as energy passes through the ecosystem's food web; ONLY 10% ofenergy is transferred from one level to the next
|
|
Predator |
an animal that kills and eats all or parts of another animal |
|
Prey |
an organism that is killed and eaten by another organism |
|
glucose |
Producers make and use these food molecules, which break down in the form of sugars. |
|
Scavenger |
acarnivore that feeds on the bodies of dead organisms / carcasses |
|
water |
What do all living things need? (It is the most abundant chemical in living things.) |
|
space |
What is a resource plants need in order for their roots to grow in the soil? |
|
glucose and oxygen |
the 2 products of photosynthesis |
|
oxygen |
a gas made by producers/autotrophs through photosynthesis |
|
carbon dioxide |
a gas made by consumers/heterotrophs (through process of cellular respiration) |
|
adaptation |
|
|
predation |
theact of an animal hunting, killing, tearing flesh, and eating another animal |
|
Herbivore |
SECOND level of energy pyramid |
|
sun |
powers the process of photosynthesis |
|
sun |
energy source for all ecosystems in the world |
|
sun |
direct energy source for producers |
|
limiting factors |
food, space, weather, disease, predators, and physical barriers can keep a population from increasing |
|
Omnivore |
an animal that eats both plants and animals |
|
niche |
an organism’s particular role in an ecosystem, or how it makes its living, or its job |
|
algae |
the producer of water, providing oxygen and food for water-dwelling consumers |
|
over-population |
occurs when a population exceeds its carrying capacity for that ecosystem |
|
resources |
all biotic and abiotic factors that an organismdepends on for survival |
|
competition |
the struggle between organisms to survive with limitedresources |
|
photosynthesis |
process by which plants, algae, and some bacteriause sunlight, carbon dioxide, and water to make food |
|
carrying capacity |
the largest population (of one species) that anenvironment can support |
