Respuesta :
Fungi, many birds, and a wide variety of insects all share the HABITAT of a tree in the forest.
Part of the NICHE of the fungi is to obtain energy from dead organic matter, such as dead wood.
Temperatures above 0°C and sufficient water in the environment help define the range of TOLERANCE for fungi.
Many species share the same habitat, but their niches vary according to the species' requirements and interaction with other species. Niches are defined by the species tolerance range. 1: habitat / 2: niche / 3: tolerance range.
---------------------------------
Let us first define the terms provided as options.
Habitat
It can be defined as the set of physical and geographical factors that affect the development of an individual, a population, a species, or a group of species.
Symbiosis
Refers to interactions between organisms. All organisms in nature interact with other organisms in different ways. Symbiotic interactions involve a relationship between two or more organisms of different species in which one or all of them turn to be beneficiated by that relationship. These species create permanent mutual dependence. There are different types of symbiosis, such as amensalism, commensalism, parasitism, mutualism.
Niche
When talking about a species' niche, we are referring to the physical space occupied by the species, the environmental characteristics of the area -pH, humedity, soil type, temperature, etcetera-, and resources availability, among others.
The species' niche depends on the especies requirements and is influenced by the interaction with other species.
- The fundamental niche is considered all the physical conditions in which a species can live, reproduce, and survive, as long as there is no interaction with other species.
- The realized niche refers to the restricted conditions in which a species can live and survive regarding environmental physic characteristics and the interaction with other species. It includes competition, predation, and other symbiotic interactions.
Energy Source
It refers to the source from which an organism can obtain the energy needed to survive. According to the species, it may be sunlight, vegetal food, or animal food.
Tolerance
The tolerance range can be defined as the range of environmental conditions between which an organism or a species is potentially capable of surviving.
When talking about environmental conditions, we are referring to abiotic factors, such as temperature, pH, latitude, altitude, salinity, humidity, radiation, etcetera. These are the limiting factors.
Knowing these concepts, we can fill in the blanks with some of the terms.
- Fungi, many birds, and a wide variety of insects all share the_hábitat_ of a tree in the forest.
All these species share the same habitat, but they probably have different niches wich vary according to the species' requirements and interaction with other species.
- Part of the_niche_ of the fungi is to obtain energy from dead organic matter, such as dead wood.
It refers to one of the fungi's requirements in particular. Getting energy from dead matter is not a symbiotic relationship, and none of the other species uses this source of energy. So it is specific to the fungi's niche.
- Temperatures above 0°C and sufficient water in the environment help define the range of_tolerance_ for fungi.
Fungi can only survive in environments with a temperature above 0ºC and enough water. These are limiting factors for fungi.
