Symbiosis
In coral reefs, we have observed a symbiotic relationship between pistol shrimps and the goby fish. The goby fish provide the shrimp protection from predators while the shrimp dig burrows for the goby fish to seek shelter in. This is an example of what type of symbiotic relationship?
Mutualism
What organisms begin every food web?
Producers
The amount of living organisms an ecosystem can sufficiently sustain is known as its
Carrying Capacity
Mushrooms and Mold are both types of Fungi. What do they both consume?
Dead organisms, because they are decomposers
Limiting Factors (resources)
*Double Jeopardy*
When a cat has heartworms, the cat is known as the _____________. And the heartworms are known as the _____________. This is an example of __________________.
Host; Parasite; Parasitism
What organisms break down dead organisms for nutrients?
Decomposers
What is the study of living organisms and how they interact with their environment?
Ecology
Grass --> Grasshopper --> Bird --> Snake
This is the food chain of a local ecosystem. This area recently had a tornado, and all of the birds have left. What organisms population will directly decrease due to the loss of birds?
Snakes because they have lost their food source
In Africa, Antelopes and Wildebeest both have the same diet and tend to drink from the same watering holes. This shared interests inevitably leads to __________________ between these two species.
Competition
In Florida, many of our trees have Spanish Moss. The Moss relies on the trees for shelter, but they do not take any nutrients from the Tree. The tree is not harmed, nor is it benefited in this relationship. This is an example of
Commensalism
Producers are eaten by
Primary Consumers
True or False:
Limiting factors are only biotic, never abiotic.
FALSE. Limiting factors are both biotic and abiotic
Seaweed --> Crabs --> Squid --> Killer Whale
Most of the Crabs in this ecosystem have been removed for human consumption. What organism will directly be impacted by this change?
The squid because they have lost their food source.
Eventually the seaweed population will become out of control which pollutes the waters, and the killer whales will have to rely on a different food source when the squid population begins to decline.
How much energy is passed through each organism in the food web?
10%
An odd pairing of the Honey Badger and Coyote combine their skills to hunt the same prey. They share any organism they catch together. This is an example of
Mutualism
Secondary Consumers
In what relationship is an organism eaten by another organism?
Predator-Prey
In a food web, how do you know what organism is being consumed?
It has an arrow pointing at the organism consuming it.
If it has an arrow being pointed at it, it means it is consuming that organism.
Organisms that consume both plants and animals
Omnivore
Flukes are organisms that migrate to the brain and spinal cord of humans or other animals after consuming bad fish. They can cause a multitude of issues and are considered very harmful. What type of organism are Flukes?
Parasites
Organisms with no known predators are referred to as
Apex Predators
How are bears a limiting factor for Fish?
They control the fish population by consuming them and their offspring.
How do producers get energy?
They use the energy from the sun and convert it into usable food (glucose) through the process of photosynthesis.
They can both consume meat (other animals)
