I just want to know if this looks good as far as the answers go and

if it all makes sense. Just want to get a second opionion before I turn it in. Also just want to make sure that bacteria is considered as a apex predator. Thank you.

Apex predator: Bacteria Teri±ary consumers: Snakes, lions, hyena, Secondary consumers: rats, wild dogs, owls Primary consumers: grass hopper, rabbit, antelope Primary producers: grass, shrubs, algae 1. Of the primary producers you selected, which one do you think has the biggest inFuence on the ecosystem you researched? Explain. I would say that primary producers would be the ones to have the biggest inFuence within the ecosystem. They are living organisms that are capable to make their own food and also tend to have the highest biomass. Grass would be the biggest inFuence speci²cally due to the fact that it is a very important source of energy within this ecosystem. Majority of the animals feed on grass as the main source of food in the forest. Grass uses the energy from the sun to make food in form of carbohydrates so that these animals are able to live o³ of this type of food source. Without grass, it would have a very nega±ve outlook within this biome and a³ec±ng majority of the animals. 2. What species did you select for the apex predator? Explain the importance of the apex predator's e³ect on the other species in your tropic pyramid. Bacteria is o´en overlooked as the apex predator. It is known to be a decomposer and consumes the dead or any other type of decaying organism within an ecosystem. Decomposers will eat these things and separate them into liµle par±cles or supplements. These supplements then go into the dirt and are broken up in water and are absorbed by plants. Decomposers can be things such as organisms, microbes, or bugs. Decomposers are able to absorb the proper nutrients that it needs to eat and are able to be essen±al, op±onal, and ter±ary purchasers. ¶or example, a worm that eats a dead plant is considered to be an essen±al customer. Then a Fy larva that eats a dead deer is considered to be an auxiliary purchaser. 3. How did the amount of energy gained compare to the amount of energy lost as heat at the 2nd– 4th trophic levels? The amount of energy in the second trophic level is considered to be higher than the amount of energy that is lost because the biomes in the second trophic will feed directly from the producers and are gaining more energy through the process of respira±on. The energy that is from the food made by plants will be used in the metabolic reac±ons or ac±vi±es within the organism. The primary consumers have more energy than the other biomes in the trophic level.

4. Referring to your completed trophic pyramid template, select one species. If this species was removed from your trophic pyramid, what would be the impact on the other species of the ecosystem? If the grass were to be removed, then this would have a big impact on the ecosystem simply because majority of the animal populaTon depends on grass as a reliable food source. ±hen as a result, there would be many animals that would die oF due to hunger. If these animals would die, then so would other consumers because they rely and feed on those animals as their food supply. It just acts as a chain reacTon. If the grass were to be gone, then so would many other things within that biome. 5. Can eForts to save a species from exTncTon be successful if the focus of preservaTon is only on that species? Explain your answer. I do not believe so because the process of conservaTon should run across all the trophic levels and the primary source of energy fall all the species should be well conserved. Saving a species exTncTon without saving its food source would not help the cause. ±he conservaTon would work best if they made it more of a priority by saving the species. 6. Considering the amount of energy required in producing animal-based foods and goods, should humans change their habits so they consume products closer to the bo²om of the trophic pyramid? Provide raTonale for your response. Humans that consume the products that are closer to the bo²om of the trophic level of the pyramid might be signi³cant when it comes to conserving energy. Humans should not only consume the animals from the primary consumers list because this would have a chain reacTon and eventually aFect the other species in the other trophic levels. If many people were to just concentrate on the biomes close to the bo²om of the trophic, there is a greater risk of disTncTon and unsustainability within the ecosystem. Reference Hairston Jr, N.
