Science Ecosystem
FOOD WEBS, PHOTOSYNTHESIS, CELL RESPIRATION AND ENERGY PYRAMIDS
| Question | Answer |
|---|---|
| Energy pyramids order | Producers, Primary Consumers, Secondary Consumers, Tertiary Consumers |
| Give an example of something that would cause competition within a population. | A location to live in between two animals. |
| If all the Eagles were to die off, what effect would this have on the herbivores? | If the eagles die off the herbivores would increase. The eagle may not eat the herbivores so they would increase in numbers. |
| Define territory. | Territory means a location that belongs to someone/something. |
| What would be an example of a third-order consumer's interdependence (think food chain) with a producer? (Look at picture on Ecosystem slides) | Eagle - Snake - Rabbit - Grass |
| Mutualism | A symbiosis that is good for both organisms that are involved. |
| Commensalism | When two organisms don’t benefit from each other; go without affecting it. |
| Parasitism | Living as a parasite (mosquito) in or on another organism. |
| Symiosis | interaction between two different organisms living in close physical association. |
| Define niche | Definition: Niche is the job of an animal in it environment. |
| Give an example of a niche | The niche of a bird is to find berries. |
| What is the foundation of all food webs? | The producers. |
| Producer: | An organism that makes its own food. Ex: Grass |
| Consumer: | Any organism that eats another organism; can’t make its own food. Ex: Ms. Hawkes |
| Decomposer: | An organism that decomposes organic matter. Ex: Fungi |
| What is the equation for photosynthesis? | Co2 (carbon dioxide) + 6H20 (water) = (light) glucose + oxygen |
| What are the reactants of cellular respiration? | Glucose and oxygen |
| What are the products of photosynthesis? | Glucose and oxygen |
| Parts of the cell used: Photosynthesis: | Chloroplast |
| Parts of the cell used: Cellular Respiration: | Mitochondria |
| Oxygen and Carbon Dioxide enter the leaves through openings called - | STOMATA |
| A plants food is sugar called - | GLUCOSE |
| Water enters the plant through the - | ROOTS |
| Plants convert light energy(sun) into - | chemical energy |
| Photosynthesis takes place in | Plants |
| Reactants of Photosynthesis | Carbon Dioxide, water, and light energy |
| Products of Photosynthesis | Oxygen and glucose |
| Photosynthesis energy is | Stored in glucose |
| Respiration takes place in | Plants and Animals |
| Reactants of respiration are | Oxygen and glucose |
| Products of respiration are | Carbon dioxide, water and chemical energy |
| Respiration Energy is: | Released from glucose |
| If humans were to leave Earth, would plants be able to survive? | Yes, Plants would survive because they go through cellular respiration that creates carbon dioxide. |
