When a harmless organism resembles a harmful one?
Batesian mimicry, where a harmless mimic poses as harmful. Müllerian mimicry, where two or more harmful species mutually advertise themselves as harmful.

What is competitive exclusion principle mastering biology?
The competitive exclusion principle states that when the populations of two species compete for the same limited resources, one population will use the resources more efficiently and have a reproductive advantage that will eventually lead to the elimination of the other species.
Why is a pathogen generally more virulent in a new habitat group of answer choices?
Why is a pathogen generally more virulent in a new habitat? Hosts in new environments have not had a chance to become resistant to the pathogen through natural selection. Human activities are transporting pathogens into new habitats (or communities) at an unprecedented rate.
What is mimicry and camouflage?
Mimicry refers to the similarities between animal species; camouflage refers to an animal species resembling an inanimate object.
When a human eats a steak a cut of meat from a cow an herbivore the human is acting as a?
When a human eats a steak, the human is acting as a _____. Secondary consumer. By feeding on a primary consumer, the human is acting as a secondary consumer.
Which of these terms applies to the relationship between the human and the deer?
Which of these terms applies to the relationship between the human and the deer? ( The human is the predator and the deer is the prey.)
Which terms best describe the interactions between species or organisms found in an ecosystem?
In ecology, the term “niche” describes the role an organism plays in a community. A species’ niche encompasses both the physical and environmental conditions it requires (like temperature or terrain) and the interactions it has with other species (like predation or competition).
What is competitive exclusion in biology?
: a generalization in ecology: two species cannot coexist in the same ecological niche for very long without one becoming extinct or being driven out because of competition for limited resources.
Why do tropical communities tend to have greater species?
Why do tropical communities tend to have greater species diversity than temperate or polar communities? Tropical communities are generally older than temperate and polar communities. Interaction increases the survival and reproductive rates of mutualistic species.
Which is the most likely explanation for why invasive species take over communities into which they have been introduced?
Which of the following is a likely explanation for why invasive species take over communities into which they have been introduced? Invasive species have a higher reproductive potential than native species.
