PRESENTATION OUTLINE
Changes to Lakes and their Animals
Cause
- The shrimp where originally in the ecosystem the shrimp.
- The shrimps main food source is found on the snapping turtles shell.
Commensalistic Relationship
Cause
- The snapping turtle chose this plant for shelter and many others.
- This plant also provides food for the turtle.
The lizards tail provides shelter for the snapping turtle but does not benefit.
Cause
- The leech found out the the turtle couldn't fight against it.
- The leach took advantage of that and started to suck it's blood
Cause
- Long ago the turtle didn't have a shell.
- Te turtle started to evolve into a shell 260 million years ago.
- The main cause, new predators.
The Predator
- The new predator was larger and stronger than the turtle.
- The turtle had no defense system and had to develop one.
- Thus came the shell.
Effect
- The hurricane did some major damage to the ecosystem.
- In secondary succession the ecosystem will start to grow back but the soil is already laid for it.
- So the plants will start to grow and then the animals and insects will start to come back to the ecosystem.
Biodiversity
- how many animals that are in the ecosystem, depends on how fast your animals will come back.
- The biodiversity of my ecosystem is very large, so animals will come back quicker.
What do humans need from our ecosystems?
- They need their resources to live their lives
WHat resources do the need?
- Well from our ecosystem they need water, food, metals, wood and living space.
How we can stop this
- WE can stop the cutting down of trees by making a park.
