Science Ecosystem

FOOD WEBS, PHOTOSYNTHESIS, CELL RESPIRATION AND ENERGY PYRAMIDS

QuestionAnswer
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.
