In the nitrogen cycle, the bacteria that convert ammonia into nitrate can be correctly identified as
nitrifying bacteria
A decomposer can be correctly defined as

List the seven main taxonomic ranks in the Linnaean classification system from broadest to most specific
Kingdom, Phylum, Class, Order, Family, Genus, Species
Give an example of an r-selected species
Mice, insects, frogs etc.
Molecular phylogeny uses which type of data to classify organisms?
DNA, RNA, or protein sequences
Give an example of an interspecific hybrid that is not fertile
Mule, Liger, etc.
Which interaction occurs when one organism kills and eats another?
Predation
Define competition
Competition occurs when two or more species compete for the same limited resource, such as food, water, or territory
Define Symbiosis
living arrangements between members of two different species, including mutualism, commensalism, and parasitism.
Define a microhabitat
A microhabitat is a small, specific area within a larger habitat that provides unique environmental conditions.
Which is the BIGGEST scale out of microhabitat, ecoregion and ecosystem?
ecoregion
Why is classifying ecosystems important for effective ecosystem management?
It provides a structured way to identify, compare, and conserve ecosystems
What is the main purpose of stratified sampling in ecology?
To make sure samples cover different habitat zones or gradients
List two ecological surveying techniques commonly used in stratified sampling
Quadrats, transects
Define Predation
Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey.
