Energy Flow
Flow and Limiting Factors
| Question | Answer |
|---|---|
| What is a biotic factor? | all the LIVING organisms in an ecosystem |
| What is an abiotic factor? | all the NON-living parts of an ecosystem |
| What is the law of conservation of energy? | Energy cannot be created nor destroyed, but it may change forms. |
| How does energy enter an ecosystem? | Through the sun, by photosynthesis |
| What are producers? | Autotrophs use sunlight to produce their own food (sugars). |
| What are consumers? | Heterotrophs obtain energy by consuming the organic matter of other organisms. |
| What are decomposers? | Detritivores eat dead matter and return nutrients to the soil, air, and water. |
| What is symbiosis? | Living things live together in relationships |
| What are the three types of symbiotic relationships? | Parasitism Mutualism Commensalism |
| What is parasitism? | One organism benefits from the association & the other is harmed. |
| What is mutualism? | A relationship where both species benefit. |
| What is commensalism? | When one species benefits and the other species is neither harmed nor helped. |
| What is a food chain? | Shows how energy flows through an ecosystem in a single pathway. |
| What is a food web? | Represents the many interconnected food chains and energy pathways in an ecosystem. |
| What are the different trophic levels? | producers, primary consumers, secondary consumers, and tertiary consumers |
| What is a trophic level? | Each step in a food chain or food web |
| How much energy is lost when going to the next trophic level? | 90% |
| How much energy is passed on to the next trophic level? | 10% |
| How is energy lost? | As heat to the universe |
| What is a population? | group of a single species living in a given area that interact with each other |
| What is a community? | multiple different species living in a given area that interact with each other |
| What is a limiting factor? | a factor or resource found in an environment that will limit the amount of growth of the populations of animals |
| What are the three main limiting factors? | Amount of food, amount of water, and amount of space |
| What is carrying capacity? | The carrying capacity of an ecosystem is the maximum amount of organisms that can exist given the provided resources |
| What is Exponential growth? | Looks like a “J” Type of growth that occurs if there were unlimited resources |
| What is logistical growth? | Looks like an “S” Type of growth that occurs if there were limited resources |
| How do you read carrying capacity on a graph? | Look at the value on the y axis when the line flattens out |
