Relationship in which one organism benefits and other is not affected
commensalism
omnivore
decomposers
variable that is measured
A decrease in an organism's predator population would lead to this
an increase in population
Relationship between organisms of different species
symbiosis
Lion is an example
carnivore
Convert sun's energy into energy other life forms can use
producers
Evidence based on scientific studies
empirical evidence
A decrease in species 1 while species 2 has a mutualistic relationship with them will result in this.
a decrease in species 2
Tapeworms are an example
parasitism
omnivore
Fungi are an example
Decomposer
Type of study in which a scientist observes organisms in their natural environment
Field study
A drought will impact this type of organism
