Questions 1. From your food web, list the herbivores, carnivores, and omnivores. Producers -Tree -Grass/Plant -Berries -Roots -Nuts/Seeds Herbivores -Grass Hopper -Worm -Rabbit -Chipmunk -Deer Omnivores -Bear -Mouse -Meadow Lark -Wood Pecker Carnivores -Wolf -Fox -Snake -Owl 2. How many food chains did you produce? I have 46 food chains in my food web. Where the top carnivore connects to the decomposer (Wolf-Worm) was not counted because it is an infinite loop. 3. Write down three different food chains from your food web. Sun - Seeds/Nuts - Rabbit - Fox - Wolf Sun - Grass/Plants - Grasshopper - Meadow Lark - Snake - Fox Sun - Berries - Chipmunk - Fox - Wolf 4. Describe where the decomposers would fit into this food web? Decomposers are …show more content…
Which organisms (producers, herbivores, carnivores, or omnivore) would be the least numerous in this food web? Explain Carnivores would be least numerous because it gets the least energy. This is because the carnivore get the producers energy indirectly. There cannot be a large number of carnivore without a lot of competition for food. 7. What would happen to your food web community if: A)All of the producers died? Explain. If producers were to die there would be no way for animals to get the energy they need to survive. Producers are vital for all organisms. If producers were to die, soon all organisms would become extinct because of the fight for food, and lack of energy B)The herbivores died? Explain. If the herbivores were to die, the producers would start to over populate. The omnivores would still be a source of how to get energy for the carnivores. The some omnivores might even adapt to become the ecosystems new herbivores. C) The decomposers vanished? Explain. If the decomposers vanished waste and remains of dead organisms would start to pile up. The nutrients that are in the waste and dead organisms would not be renewed back into the ecosystem. Therefore the producers would not have enough nutrients since decomposers were not there to make new
One of those relationships, food webs, has an important function of transferring energy and keeping the biological lifecycle going by the various lifeforms feeding off one another. The concept of energy transfer that goes on in food chains in ecosystems keeps organisms living by the energy the body needs being provided when they eat other organisms, as supported by the studies of “food chains, food webs, and trophic levels.” It is important that we continue to observe ecosystems like the Everglades Hardwood Hammock in order to help preserve them. (Arms,
them into the autotrophs and secure their position at the bottom of the food chain,
This in turn would lead to more consumption at the top of the food chain, eliminating the predators to creatures at the lower end
Say a frog eats a caterpillar, then a snake eats the frog, then finally a owl eats the snake. This is just a simple food chain but something called biodiversity, which means that’s there is a variety of things a that one animal can eat. An owl cant only eat a snake it could eat the frog or something smaller like a worm. This keeps form one species dying out completely, which would cause multiple species to die out. When someone releases a pet into the wild they are causing a disturbance into the wild habitat. When a python is released into a place full of crocodiles these two will start competing for food which would cause all of the lower species to start lowing in numbers faster until they become extinct which would then make the snakes and the crocodile die off too. If this keeps on happening the eventually every animal would die off!
The position is called a trophic level. For example, fox eats birds, so if the food chain contained a fox and a bird then the fox would be at a higher trophic level then the bird.
Text Selection: This selection, taken from the young readers edition of Pollan’s bestseller, The Omnivore’s Dilemma, asks students to consider how their food is grown today and why and how that has changed. This brief history and science of United States farm ecology offers students diverse opportunities for exploration and close reading.
-Reintroduction of a top predator lowered the number of over grazing herbivores, leaving a more stable amount of food for many species of herbivores.
Which two organisms (species) from your sample had the lowest relative abundance? On what do these two
It’s a simple shape with three points and equal sides that can easily be recognized by a kindergartener, but it’s labyrinth of content is rightfully one of the most perplexing problems for the American adult. Highly acclaimed, heavily insightful, and haltingly honest, The Omnivore's’ Dilemma by Michael Pollan, attempts to navigate us through the food chain—the Bermuda Triangle we encounter in our everyday lives. Pollan analyzes the origins and effects of three varying food chains that support the American diet: industrial food, organic food, and food via hunter and gatherer. His impressive and in depth inspection amplifies his warning against mindless food consumption and justifies his warrant that all Americans should be wary of what is on
Animals would not have any food to eat, they may not grow and food will be scarce. Animals that live on or in trees will be left homeless
The average omnivore has a variety of food to pick from. This adds to the omnivore’s dilemma.unlike monarch butterflies who only eat one type of food us omnivores eat just about anything. But something to point out is that as humans we eat such a large variety
The exact scenario changes in each example, but the central idea remains that through a chain of interactions, a non-abundant species has an outsized impact on ecosystem functions.
Carnivores rely on hunting animals for food, thus their survival depends on their ability to catch their next meal. These carnivores often strive for the biggest prey, making food harder to attain and increasing the overall energetic demand. Hunting becomes a game of stealth, fear and maintaining energy levels (Brown et al. 1999). Two reports were done by Scantlebury et al. (Scantelbury et al. 2014) and Williams et al (Williams et al. 2014) and they looked at the delicate balance between the depletion and replenishment of energy in order to survive. The study found that pumas and cheetahs have different game strategies when it comes to hunting. Pumas prefer the sit and wait approach as they would rather let the prey come to them, while cheetahs
Insects and small mammals. When fall comes near, a black bear must eat large amounts of food in order to gain enough
The number of producers compared to the number of consumers is less than the consumers. The amount of primary consumers is three while the secondary are three and the tertiary are four. The trophic levels these feeders animals occupy are second, third and fourth trophic levels. Also known as primary, secondary and tertiary consumers. The animals that form these trophic levels are rabbits, birds, deer, mountain lions, fox's, coyotes, owls, eagles hawks and falcons.
