Biotic Factors : Living organisms in an ecosystem.
Antelope Elephant Tree
Porcupine Desert Lily
Bats Desert Willow Tree
Snake Desert Marigold
Abiotic Factors: Non-Living Factors in an ecosystem.
Carrying Capacity and Changes in Populations : The number of people, other living organisms, or crops that a region can support without environmental degradation.
IF someday a snakes main meal would be extinct, most of the snake population would decrease dramatically. Especially with other forces such as, natural disasters, human destruction, and etc...
Resources needed for a population to survive:
Limiting Factors: Any factor or condition that limits the growth of a population in an ecosystem.
Extremely hot temperatures
Unbalanced predator/prey community
Unbalanced Carrying Capacity factors
(such as less food, more food, less space, more space, etc...)
Psh minimal water... more like no water
Energy Roles: They are determined by how the organism gains energy and how it interacts with other living things in its ecosystem.
Energy Roles in an ecosystem: The Desert
Herbivore : Camel
Carnivore : Banded Gecko
Omnivore : Roadrunner
Scavenger : Vulture
Producer: Prickly Pear Cactus
Decomposer : Beetle
The 3 main types of energy roles are producers, consumers, and decomposers. In the consumer energy role, there are subset energy roles such as herbivores, carnivores, omnivores.
Producers are vital in an ecosystem because of its energy transfer from the sun. It takes the radiant energy and transforms it into chemical, followed by chemical to mechanical energy. It basically produces all of the food that 1st level consumers eat, and then continues on until another level consumer eats it. So without the producers, no animal or human can live.
Food Chains and Food Webs
Food webs would be more realistic than food chains because of all the possibilities that can open on a web. In a food chain, it only stretches out for a line, but a food web can help better express the full potential of all the countless contingencies.
For this particular food web, if we were to eliminate the scorpion population, then the insect population would have a increase in size, with Large lizards now being the only predators. . The Large lizard population might increase due to more food. With insect population increasing, less producers would be alive to support other animals, and slowly ending the world. But that topic is for a different time. :)
Trophic Levels and Energy Pyramids
The reason behind the use of a pyramid other then a cylinder or a cone, is because it decreases in size as it gets to the top, representing less energy as it goes to the top.
As for having the largest base for producers, producers have the most energy, and it is smaller at the top because of life processes that transfers less energy.
What is absolutely need for photosynthesis are sunlight, chlorophyll, carbon dioxide, and water. As for what photosynthesis produces, its glucose, oxygen, and water.
Tropism: Turning of bending movement of an organism toward or away from an external stimulus, such as light, heat, or gravity
A tropism for the desert ecosystem would be the cactus plant with photo tropism. Since it is out there in the desert, it gets its major growth nutrients from the sun.
These tropisms help the plants survive because without a photo tropism, the plants wouldn't grow. Without plants in the desert, everything eventually will perish.
They don't even need toilet paper...
Decomposers- Break down dead and decaying organisms.
Some of the only decomposers in the deserts are bacteria and millipedes. With the other typical decomposers not being present due to minimal moist conditions.
The whole purpose of having adaptations is so that it can survive. Adaptations help animals survive by giving them certain characteristics to live in that environment. Some of the different types of adaptations can be a thick coat of fur on a polar bear in the north pole. Another example could be how sharks have fins to swim more efficiently in the marine biome, and without it, it would die.
There are a few different adaptations that an animal could have. Structural, and behavioral. Structural is how it looks with its physical appearance, and behavioral would, of course, be how it acts and behaves due to certain conditions.
A popular adaptation is to stay under the shadows of large objects or digging burrows in the ground to protect from the sunlight. A popular adaptation for plants is that they reach deep into the ground with their roots and abtaining water from underground.
Placing an organism into a different ecosystem would change its life style and eventually cause it die. If we were to put a rattlesnake in the marine biome, not only could it not get food, it would drown and die trying to grasp for breath. After it runs out of its breath it would sink to the bottom to be never heard from again.
Adaptations: Process of an animal to be fitted in its environment :)
Natural Selection: The process whereby organisms better adapted to their environment tend to survive and produce more offspring.
A natural selection would be a camels foot because it gets flatter when it get don't the sand. The population of the camels increased. The sand is the natural thing that made the camels have flatter feet.
