ECOLOGY | the study of the interactions among living things ad between living things and their surroundings.; Greek word is Oikos, which means house |
WHAT ARE THE LEVELS OF ORGANIZATION | Species, Population, Communities, Ecosystem, Biome |
SPECIES | Group of organisms so similar to one another that they can breed to make offspring. |
POPULATION | All the individuals of the same species that live in the same area |
COMMUNITIES | A group of different species that live together in one area |
ECOSYSTEM | All the organisms as well as the non-living things given in an area. |
BIOME | A major regional or global community of organisms with life.
EXAMPLES: Tundra, Desert, Coniferous Forrest, Deciduous Grasslands, Mountains, Forrest, |
BIOTIC | A living thing EXAMPLES: Plants, Animals, Fungi, |
ABIOTIC | A non-living thing EXAMPLES: moisture, temperature, wind, sunlight |
ENERGY | what is at the core of every organism's interaction with the environment to power life's processes. |
WHAT IS ENERGY NEEDED FOR | To move, make new cells, to grow, to carry out chemical reaction |
PRODUCERS | Organisms that get their energy from non-living resources means they make their own food |
ANOTHER NAME FOR PRODUCERS | Autotrophs EXAMPLES: plants, fungi, and bacteria |
WHAT IS THE MAIN ENERGY SOURCE FOR LIFE ON EARTH | Sunlight |
HOW MUCH OF A PERCENTAGE OF THE SUNLIGHT IS USED | Less than 1% |
PHOTOSYNTHESIS | Process where autotrophs use light energy to make carbohydrates |
WHAT IS ADDED DURING PHOTOSYNTHESIS | Oxygen |
WHAT IS TAKEN AWAY DURING PHOTOSYNTHESIS | Carbon Dioxide |
WHAT IS MADE DURING PHOTOSYNTHESIS | Glucose |
ANOTHER SOURCE OF ENERGY FOR LIVING THINGS IS | in organic chemical EXAMPLE: meat, plants, etc. |
CHEMOSYNTHESIS | The process by which an organism forms carbohydrates using chemicals rather than light as an energy. |
CONSUMERS | The process by which an organisms forms carbohydrates using chemical, rather than light as an energy source. |
WHAT ELSE CAN A CONSUMER BE CALLED | hetertrophs |
WHAT ARE THE TYPES OF HETERTROPHS | herbivores, carnivores, omnivores, detrivores, decomposers |
HERBIVORES | organisms that only eat plants |
CARNIVORES | eat only animals |
OMNIVORES | eat both animals and plants |
DETRIVORES | eat dead organic matter |
DECOMPOSERS | break down organic matter into simpler compunds |
FOOD CHAIN | Sequence that links spcies by their feeding relationships. |
LAND EXAMPLE OF THE FOOD CHAIN | grass>carrot >bunny>cheetah |
AQUATIC EXAMPLE OF THE FOOD CHAIN | algae>plankton>fish>shark |
FOOD WEB | model that shows the complex network of feeding relationships and the flow of energy within an ecosystem |
TROPHIC LEVELS | levels of nourishment in a food chain |
WHAT MAKES UP THE FIRST TROPHIC LEVEL | producers |
WHAT MAKES UP THE SECOND,THIRD, OR HIGHER TROPHIC LEVELS | consumers |
WHAT DOES EACH LEVEL IN THE PYRAMID RELY ON | energy |
ECOLOGICAL PYRAMIDS | a diagram that shows the relative amounts of energy or matter contained within each trophic |
