what is an organism?
It is an individual that has a cellular structure and can independently perform basic life functions.
symbiosis
A close and long-term interaction between two different species.
mutualism
It is when two organisms both benefit from the interaction.
commensalism
It is a relationship that benefits the organism, and the other organism isn’t affected by it.
ammensalism
It is an interaction between organisms whereby one organism is suffering, and the other isn’t affected by it.
parasitism
One organism lives in a host and benefits from it by causing harm.
what are the two types of predation?
Herbivores
True Predators (carnivores)
what are the two types of competition?
Intraspecific
Interspecific
what are the four types of partitioning?
Resource
Temporal
Spatial
Morphological
what is a predator-prey relationship?
A biological interaction where the predator hunts and kills another organism, which is the prey, for food.
do parasites kill their host?
No, parasites who use a host does not intend to kill their host. However, they harm their host as they live within.
parasitoid
the eggs are laid inside the host and will eventually kill the host.
competitive exclusion principle
Species who compete for the same limited resource cannot coexist at constant population levels.
resource partitioning
The species use the same resource in different ways to reduce competition.
temporal partitioning
The species use the same resources, but at different times.
spatial partitioning
The species live specific areas or habitats where the desired resource is just within their range.
morphological partitioning
When different species divide or share their resources based on their body feature.
what does intraspecific competition mean?
Competition between the same species
what does interspecific competition mean?
Competition of different species
limiting factor
An abiotic factor limits or prevents the growth of a population.
