Transcript of Ecology

Ecology- interactions among organisms and their environments. It shows the relationship with living and non-living things also known as biotic and abiotic factors.

Abiotic Factors
Abiotic Factor Examples
Oxygen. Oxygen is needed by all plants and animals in order to live and function. Compounds for carbon and energy are necessary to provide maintenance and growth.
Biotic Factor
A living thing, as an animal or plant that influences or affects an ecosystem.
Biotic Examples
Flowers also known as Bellis perennis
Biotic and Abiotic
Both abiotic and biotic factors determine both where an organism can live and how much a population can grow.
Natural home or environment of an animal, plant, or other organism.
Sunlight. It's used in photosynthesis along with carbon dioxide to make oxygen and sugars for organisms.
Soil. Soil provides ecosystem services critical for life:
soil acts as a water filter and provides habitat for many organisms
A nonliving condition that influences or affects an ecosystem and the organisms in it. Biotic and Abiotic factors are ways to identify how certain ecosystems are different from others.
Tree also known as Quercus
Water. Water plays vital roles in ecosystems. Although many other substances are necessary for life and for ecosystems to exist, without water nothing else would function to produce life.

Bird also known as an Ave
My Ecosystem
Out of all the ecosystems out there, the main one that i happened to use was my backyard. It is the perfect ecosystem because of the different biotic and abiotic factors that live within this ecosystem. It is a habit for certain animals and a way to interact with other species, plants and more. It is a beautiful ecosystem providing flowers, trees, sunlight, soil, and different come and go such as birds, rabbits, squirrels, and more.
The main biotic and abiotic factors that work together to make up a beautiful ecosystem.
Animals- Water may be consumed by living things, or can also be a habitat for them. Animals that use water as their habitat or home rely on water more. Animals also need water to carry out cell activity. Some animals drink water regularly to keep hydrated, digest food and build body fluids.

Plants- All plants need sunlight for a process called photosynthesis. This is where light, energy, carbon dioxide and water interact within the plant to produce the sugar it needs to survive.
Apple also known as Malus Pumila
Trees- Trees need oxygen to survive. They take in oxygen, give off carbon dioxide. Without oxygen, trees will soon suffocate.
Groundhog also known as Marmota Monax
Grass/ Soil
Underneath a Rock- The habitat of a rock is unique because it is a good hiding place or many animals. Underneath the rock you will find many organisms that build a home is the soil.
-a large open area of covered with grass. Soil is their to provide life for other organisms.
A niche refers to the way in which an organism fits in to a community or ecosystem.
Squirrel Nest- Squirrels tend to build this hole not mainly sleeping but for food and safety at times. Most squirrels build this tree hole and then if you look upward on the same tree you will see a nest where they sleep at times.
Animals such as squirrels and birds use this as their habitat.
Animals such as snails and ants use this as their habitat.
Animals such as worms and woodlice use this as their habitat.
Geese Niche- The role that a goose plays in an ecosystem is dispersing seeds of the plants that they eat.
Flowers Niche- The purpose of flowers are for reproduction. They also produce pollen for other organisms to use to survive.
Rabbit Niche- The role that a rabbit plays in an ecosystem is that is it prey for most animals such as foxes, raptors, cats, ferrets, and raccoons. Rabbits have a high reproductive rate which makes them integral to the food chains, as they consume plants.
Levels of Organization
Organism- an individual animal, plant, or any life form.
Population-group of individuals of one species in a given geographic area.
Communities- an area that makes up more than one population
Symbotic Relationships
Mutualism- relationship where both species benefit from each other.
Commensalism- relationship between two organisms where one benefits and the other neither benefit or is harmed.
Parasitism- relationship between species, where one species(the parasite) benefits of the other species also known as a host.
The tree is a home for the squirrel. The tree is just a host for the squirrel but isnt harmed nor affected.
Dog is blood and food for the tick but the dog is unlucky because it wil get a disease and possibly die.
Lichen gives the tree nutrients and the tree gives lichen life support.
Tree and Lichen
Squirrel and Tree
Dog and Tick
Energy Transfer
Transforms sunlight to make glucose
An organism that is dependent on others because it can not synthesize its own food.
An organism that feeds on or breaks down dead plant or animal matter
Food Chain
a series of organisms each dependent on the next as a source of food.
Mushrooms dont have chlorophyll therefore they cant make their own food. It releases enzymes that decompose dead plants and animals.
Plants can create glucose
Fish eat other organisms to live such as other fish and snails.
Strawberries produce energy and are located on the 1st level
Rabbit are consumers on the 2nd level
Goose consumers on the 2nd level
Domestic Dog are consumers on the 3rd level
Human are consumers on the 3rd level.
Grains produce the most energy since they are on the 1st level
Food Web
a series of organisms related by predator, prey and consumers that are interdependent food chains in an ecology community.
Food Pyramid
a graphic representation of predatory relationships in the food chain, where various forms of life are shown on different levels, with each level preying on the one below it.
Group of trees
Trees, soil, oxygen fish and sunlight help give life to the organisms.
