Producers and Consumers

Apple seeds are what creates apple, but basically no one would eat apple seeds except for animals, or sometimes we eat it, especially when we're too lazy to throw out the apple seeds from the apples we are eating, but enough about that, I'm gonna talk about the food web for an apple seed, or just basically how the food web works.

One of my producers are apple seeds. Which are eaten by a birds or a humans, but since no one eats humans I choose birds. A bird is one primary consumer of an apple seed. It eats these seeds because it's in one of their food chains, if not then worms. Birds are creatures who have wings for them to use for traveling, migrating. One of it's predators are snakes, they are creatures that eats about almost anything, even their own companions! Snakes are my secondary consumer who eats the birds who eats the apple seeds. Snakes are somehow poisonous, especially when it bites you. Snakes have a lot of enemies in the wild ares, like snakes themselves, bears, alligators, coyotes, or even birds! How the tables are turned. OK, so for my snake, i'll just choose coyotes as it's enemy. Coyotes also have great amount of tertiary consumers, but for one, I know that coyotes hates wolves. So there it goes for my first food web, from apple seeds-birds-snakes-coyotes-wolves.!
















My second producer are dead plants. Dead plants/rotten, are disgusting, they really are, I mean not the others, but the one's who reeks. Dead plants are eaten by a lot of insects, like slugs, worms, or even beetles. But for now, my primary consumer would be worms. Worms are invertebrate animals, with long slender soft bodies and no limbs, ok just typing this down gives me the shudders. But, worms are the primary consumer of dead plants, they sometimes seeps its remaining nutrients and goes off. Worm's secondary consumer would be turtles, their are some other animals or creatures that eats worms, but for now I'm writing down turtles. Turtles are sea creatures who only goes to land for giving birth, one of it's main predator would be an eagle, american eagle? Maybe, but yes an eagle. Eagles are a large bird of prey, with a massive hooked bill and long broad wings. Although most eagles are carnivorous the African Vultinure Fish-Eagle is primarily a vegetarian, feeding on rich oil palm fruits. Eagles don't really have any others predators/enemies but themselves, since they are mostly up high in the air trying to look for their prey.





So, this is my last producer, and it'll be cycads. Cycads are seeds plants typically  characterized by a stout and woody trunk with a crown of large, hard and stiff, evergreen leaves. So, for my last producer, I'm going all out! I'm going back to the age of time! Don't know if that makes sense, but yeah. Cycads are eaten by triceratops, yes a dinosaur, I think. But yeah, triceratops are large quadrupedal herbivorous dinosaur living at the end
of the Cretaceous period, having a massive head with two large horns, a smaller horn on the beaked snout, and a bony frill above the neck. While Triceratops are cycads primary consumer, T-rex is triceratops secondary consumer. It eats the triceratops. T-rex or Tyrannosaurus, is a genus of coelurosaurian theropod dinosaur. T-rex doesn't have any tertiary consumer, since T-Rex's are the King of the jungle before. Some other dinosaurs are the same height of the T-rex, but since it's the King, no one dares to challenge it. So that's all I guess, for my food web. Thank you for reading!

Cellular Respiration

Overview of cellular respiration- Plants use photosynthesis to make their own food. Animals eat other organisms as food, but food is not a direct source of energy. Instead, plants, animals, and other eukaryotes break down molecules from food to produce ATP. Photosynthesis and cellular respiration are not true opposites, but you can think about them in that way. The Krebs cycle produces molecules that carry energy to the second part of cellular respiration. The chemical equation of cellular respiration is also basically the reverse of photosynthesis, but the structures of chloroplasts and mitochondria are similar.



Learned- I learned that cellular and photosynthesis are not true opposites. That plants use photosynthesis to make their own food, but it is not the source of energy. As it is said, mitochondria cannot make ATP from food. First food is broken down and turned into glucose, and then glucose breaks down and splits itself into two or three molecule and makes two molecule of ATP. Three carbon molecules are broken down in a cycle of chemical reaction. It is then transferred to the second stage of cellular respiration, and then the energy of it is transferred to a chain of proteins in the inner membrane of the mitochondria. Then a large number of ATP is made.


Cellular respiration- like photosynthesis, is a very complex process, like glucose and oxygen do not react directly with one. Glycolysis is an ongoing process in all cells.. It takes place in the cytoplasm before cellular respiration, and it does not require oxygen. Although glycolysis makes four ATP molecules, recall that two ATP molecules are used to first split the glucose molecule. The electron transport chain takes place in and across the inner membrane of a mitochondrion. As with electron transport in photosynthesis, proteins make up the electron transport chain in cellular respiration.


Learned- I learned that photosynthesis is a very complex process. Cellular respiration makes more ATP molecules than glycolysis does. That the Krebs cycle’s main function is to transfer high energy electrons to molecule that carries them to the electron transport chain and also that this cycle is sometimes called the “citric acid cycle” because the citric acid is the first molecule formed. That photosynthesis stores energy as a chemical energy, while cellular respiration releases stored energy as an ATP and heat.
