Ibukun's Inquiry project
My Question
How do symbiotic relationships affect our ecosystem?
What is symbiosis?
A symbiotic relationship is where two or more different species closely depend on each other. This may or may not benefit each member
What Are The Types of Symbiosis?
There are three types of symbiotic relationships
a)parasitism- is when one organism the parasite feeds off from the other organism/species. The parasite sucks up nutrients from the host. This relationship type is definitely not good for the host.
b)commensalism-where one of the species gets food or benefits while not affecting the other member of the relationship. Commensal relationships are one way!
c)mutualism-mutal relationships are when two species work together! They each benefit each other
of parasitism, commensalism, mutualism
An example of a parasitic relationship is the one between leeches and humans. When a human goes swimming on a leech's home which is a lake or pond,a leech(the parasite) feeds on human blood which has lots of nutrients. The unlucky person gets nasty side effects like these and may loose a lot of blood.
the porcelain crab hides behind sea anemones and waits to grab fish that get stung by the anemone. The crab does not harm the anemone. Their relationship only benefits the crab
One of my favourite symbiotic relationships that you may recognize is the anemone and clown fish. you may see this from the classic Disney film Finding Nemo. The clown fish is the only fish that can live with the anemone because they have a slimy mucus on them that protects them from getting stung. The anemone offers protection to the clown fish from predators while the clown fish eats small fish off from the anemone and lets the anemone to breath better because of how the clown-fish swims around the anemone.
How do symbiotic relationships affect our ecosystem?

What is an Ecosystem?
Definition: an ecosystem is a biological community of interacting organism and their physical environment.

An ecosystem is made up of living and non-living things. Also called biotic and abiotic things.

A population is a group of the same organism living in the same place at the same time.
The habitat needs to have elements to keep those organisms alive. e.g.)food, water,oxygen , minerals,and temperature.
what are in ecosystems?

Different populations have their own habitat. In most habitats different populations share that habitat. such as in a cave, many species co-exist in that cave or in the sea, lots of different plants and animals live in that sea together.
So in an ecosystem the organisms depend on the water and energy(sun) to survive. That's how they compete for these and there are predators and prey.
How Does Symbiosis Affect their Ecosystems?
please take a look at the habitat and ecosystem diagrams being passed about the class
These factors interact with each other making the ecosystem
What Are The Types of Ecosystems?
Terrestrial Ecosystem: If the ecosystem is outside of water it is called a terrestrial ecosystem. Such as ecosystems in rainforests or deserts.
Aquatic ecosystem: If the ecosystem is in a body of water it is called an aquatic ecosystem.
Here's a fun video about symbiosis

One of the species benefits while the other does not

One of the species benefits but the other species is not effected positively or negatively
Both species benefit from the relationship
More About Ecosystems
Ecosystems come in different sizes.
Here are the 3 main scales of an ecosystem

Micro: A very small ecosystem (size)
Messo: medium size ecosystem
Biome: very large ecosystem or collection of ecosystems with similar living and non-living things
What are in Ecosystems?
In each ecosystem there are habitats, where a populations live.
What are the parts in an ecosystem?
Individual:any living thing or organism
Population: as mentioned before, a group of individuals
Community: all populations living in the same area
Ecosystem: a community living organisms interacting with the environment.
Biome: sets of ecosystems in a location
All ecosystems on earth

How do animals in an ecosystem relate to each other?
Living things need food to survive. Food also provides energy. Without energy plants can't grow. Animals also use energy to grow, move, and breathe. A lot of the energy on earth comes from sunlight. Green plants use the sunlight for food. When herbivores in the ecosystem eat those plants, they get dome plant energy too and a carnivore eats those herbivores.
There is a food chain going on in the ecosystem
Forest ecosystem: There are many animals in a forest but here's a simple food chain for the animals in the ecosystem
of grass is consumed by the population of deer which get eaten by the wolves in that ecosystem.
Kalman,Bobbie and Langille,Jaqueline.
What are Food Chains and Food Webs? New
York: Crabtree Pub. Co.,1998.Print
Every living thing in an ecosystem has it's own part.
:Do you notice that more the same animal is on different levels on the pyramid? That is because he same animal can fit on both places on the pyramid they can eat anything below them.
Food webs and food chains are very important parts in an ecosystem. It's the transferring of energy of one organism to the other. Remember from before all living things need energy to survive, which is food.

The energy source that provides plants food is the sun. All food chains begin with the sun
Book reference
Now we know about ecosystems. In ecosystems there are animal relationships called symbiosis
When there is symbiosis in an ecosystem there is a less chance the species in the relationship will get eaten especially in mutualistic relationships.

One of the clownfish's predators are sting ray. But with the symbiotic relationship between the anemone and the clown fish. The anemone is safe for a while.

Quick Quiz

1. What is a symbiotic relationship?
2.What is always first in a food chain?
3.what two factors make an ecosystem?


I hope you learned something new. Now to the bibliography
What is it Made up of?
There are levels in an ecosystem
What is a food chain?
who eats what?
There are two main types of ecosystems
at te end of this food chain a decomposer such as fungi or bacteria eats the dead carnivore.
that is called a
see if you can find who eats what.
