Biotic Factors- Living factors in an ecosystem.

Biotic Organisms:

Mangrove Anole


Mangrove Yellow Warbler

White Crowned Pigeon

Wood Storks

Tree Crab

Mangrove Tree

Abiotic Factors- Non-Living factors in an ecosystem.

Abiotic Factors:

Warm water


Humid climate



Carrying Capacity- The largest number of individuals off one species that an environment can support

The Mangrove Leaf Miner eats the leaves of the Red Mangrove.

The Leaf Miner depends on the Red Mangrove to survive. So that means that if there are no Red Mangroves to eat the population of the Leaf Miner will decrease in size. That also means that if their are not a lot of Leaf miners then the population of the Red Mangrove will grow.

This is a leaf that was eaten by a leaf miner. Where you see white used to be green but after the leaf miner was done with it, it looks like this.

Limiting Factors- any factor or condition that limits the growth of a population in an ecosystem.

Limiting Factors of a Mangrove



One Predator Prey relationship in the mangrove is between the Mangrove Anole and the cricket. The Anole uses its speed an technique to catch and eat the cricket.

When it floods on a mangrove it can kill many of the crickets and the Anole does not have anything to eat. This is how limiting factors affect this predator prey relationship.

Energy Roles- determined by how the organism gains energy within the ecosystem.

Examples of energy roles.

Red Mangrove Tree- Producer

Mangrove Leaf Miner- 1st Level Consumer

Mangrove Yellow Warbler- 2nd Level Consumer

The Red Mangrove Tree receives its energy from the sun.

The Mangrove Leaf Miner receives its energy from the Red Mangrove Tree.

The Mangrove Yellow Warbler receives its energy from the Mangrove Leaf Miner.

Why are producers vital to an ecosystem?

Producers are vital to an ecosystem because without them the rest of the ecosystem would not survive.

This is because producers are the base of the food web.

Food Chains and Food Webs.

Why are food webs more realistic than food chains?

Food webs are more realistic than food chains because organisms can eat more than one type of food to get their energy.

If one organism were removed from the food web the population of the organism it eats would increase and the increasing population would eventually make the organism it eats go extinct.

Trophic Levels and Energy Pyramids

Trophic Levels

Tertiary Consumers (top carnivore, 3rd level consumer, carnivore/omnivore) 1 kcal

Mangrove Wood stork

Secondary Consumers(carnivore/omnivore, 2nd level consumer) 10 kcal

Mangrove Yellow Warbler

Primary Consumer(1st level consumer,  herbivore/omnivore) 100 kcal

Mangrove Leaf Miner

Producers(autotroph, plants) 1000 kcal

Red Mangrove Tree

The energy pyramid is represented by a pyramid because it show how as the trophic level goes up less energy is provided.

Producers have the largest level of the pyramid because they have the most energy. The top carnivore has the smallest level of the pyramid because it gets the least amount of energy.


Photosynthesis Chemical Equation

CO2+H2O ---> C6H12O6+O2

The things needed for photosynthesis are sunlight, water, and carbon dioxide.

Photosynthesis takes place in the chloroplast.

Radiant energy --> Chemical energy


A directional movement responses that occur in response to a directional stimulus.

Flowers Leaning towards the sun.

These tropisms help the plants in my ecosystem survive by giving them sunlight, water and other things.

The Role of Decomposers

Decomposers are vital to my ecosystem because they help return nutrients to the soil so that the plants can absorb them and restart the cycle. If there were no decomposers the plants would not get the nutrients and not grow.

The decomposers in my ecosystem are mostly bacteria and protozoans, and amphipods.


Adaptations are important because the animals that live on a mangrove have a lot to adapt to such as living on the water and moving between trees.

Some adaptations would include: having a very strong root structure, being able to climb trees, eat mostly plants, and retain very much water.

If an organism from my ecosystem were to be put in a desert it would have a lot of trouble finding food and water. It would need very green leaves and a lot of water because it is used to  a very wet climate and ecosystem.

Natural Selection

The gradual process by which heritable biological traits become either more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment. It is a key mechanism of evolution.

An example of natural selection is in the plants of my ecosystem. They were naturally selected with roots that can filter out salt crystals in high tide and breathe oxygen in low tide. They do this because in high tide plants can't just take salt water but the y have to filter it out, and in low tide their roots don't reach the water so they have to take in oxygen.

Good job with the organization

I like your organization. Don't forget that you have to include the four types of consumers. (carnivores, omnivores, herbivores, and scavengers)
