Cold Water Sun

Hot, humid Climate
Carrying Capacity- the largest number of individuals of one species that an environment can support.
Food, water, shelter, and space
The population specific to my environment can change over time depending on the resources. If there's plenty of resources, the population will live and gradually get larger, but if the resource supply minimizes, then the population with slowly decrease because of the lack of needs for survival.
Limiting Factors- any factor or condition that limits the growth of a population in an ecosystem.
1) Too much rain so a flood occurs, wiping out all the food sources for animals that live on the floor of the rainforest 2) Global warming continues making the climate almost unbearable for animals incapable of handling hotter, more humid climates and weather.
The jaguar is a majestic cat that hunts many things such as: Deer, Capybaras, fish, and turtles. This affects the population of the prey of this animal, but has its ways of affecting the predator itself. Some jaguars may have to compete for a resource in case of shortage which can cause them to fight and kill for it or the animal itself die because of the lack of a resource.
Energy Roles- determined by how the organism gains energy and how it interacts with other living things in its ecosystem.
Producers- Elephant Ears, Tall grass- Get their energy from the sun
Consumers: Herbivores- Capybara, Howler Monkey, Tapir- Get their energy from either producers only (plants only).
Omnivores- Poison Dart Frog, Spider Monkey, Red-eyed Tree Frog, Toucans, Sloth- Get their energy from eating plants and/or animals
Carnivores- Jaguars, Boa Constrictors- Get their energy from only eating other consumers (meat only).
Scavengers- King Vulture, Army Ants, Giant Millipede- Get their energy from dead orgamisms
Decomposers- Saprophytes, Fungi- Break down dead organisms and return the nutrients to the environment
The role of the producers is very important. Producers are the base of every environment and they are what start the energy transfer process. They give their energy to organisms that consume them and they give their energy to what consumes them.
Food Chains and Food Webs
Food webs are more realistic than food chains because they show more possibilities of organism consummation. It shows how many things one organism can consume.
If I removed one organism from this food web, for example, the python, then the things that the python would eat would increase in size and possibly over populate the ecosystem.
The shape is a pyramid because it shows how the energy supply gets smaller as the stages go on. If it was a different shape, like a cube or sphere, then the energy flow wouldn't be shown correctly.
The producers are at the bottom because they are the BASE of an ecosystem. They start the energy flow and they also provide oxygen for living things. Top predators are at the top because they are almost the final stage of the energy and there is less energy at the top.
CO2 + H2O -turns to- C6H12O6 + O2
What is needed for photosynthesis to occur?
You need sunlight, water, and CO2 for photosynthesis to occur and glucose and oxygen are created during this process.
Radiant energy turns into chemical energy.
Tropisms- turning or bending movement of an organism toward or away from an external stimulus such as light, heat, or gravity.
Examples: Canopy trees growing away from the force of gravity and toward the sun.
Roots of plants growing toward the force of gravity.
Some certain types of plants responding instantly to touch (thigmatropism)
Tropism helps plants survive because they locate where the sunlight is so they can make their food and survive. Also it helps them respond to internal and external hardships or benefits.
Decomposers are very important to my environment because they help get rid of all animal waste as well as all the dying or decaying things in the environment. They are nature's recyclers. Without decomposers, the entire world would just be an above-ground graveyard. There would be nothing to get rid of all of the dead organisms and waste. The earth would be a wasteland.
Types of decomposers in my ecosystem are:
-Fungi (Oyster Mushrooms, Cup Fungus, etc.)
The importance of having adaptations is to allow an organism/animal to adapt to climates, situations, trouble, etc. They help an organism survive in their environment or a new environment because they can change something about them whether it's behavioral or structural. They keep animals alive and well and help organisms to deal with natural hardships. The animal/plant changes to adapt to something new.
The two types of adaptations are structural and behavioral
- Snakes shedding their skin when it gets too small.
- Red eyed tree frogs blending in to the leaves of the rainforest.
- Venus fly trap closing on its prey.
Natural Selection- the process in nature by which organisms that are better adapted to their environment tend to survive longer and transmit more of their generic characteristics to succeeding generations than do those that are less well adapted.
If I placed a venus fly trap in the arctic, then the plant would have hardly anything to eat and also not enough sunlight. Without the main things for a plant to make photosynthesis, the plant would soon lose the food supply and die off and the offspring would be the same.
Natural selection is important because it allows the organism to blend in to what surrounds them. It mainly goes hand in hand with camouflage because it helps an organism not to be seen in a certain environment. Also, natural selection transfers into the offspring, thus transferring the traits, as the traits change over time, into an infinite cycle.
The animal that I chose for natural selection is the red-eyed tree frog. It blends in well to its environment because of its green color, but also stands out because of its bright red eyes, neon green skin, and blue sides. The environment has changed due to deforestation . The population is gradually decreasing because of this. Deforestation has caused these frogs to lose their homes which can sometimes be crucial for reproduction. When the frog would reproduce, the traits would be transferred into the offspring, but possibly altered a little.
