how do endangered animals affect the earth?
Answer:
Explanation:
When a species becomes endangered, it is a sign that the ecosystem is slowly falling apart. Each species that is lost triggers the loss of other species within its ecosystem. Humans depend on healthy ecosystems to purify our environment.Match the definition/description with the correct term.
A. Character displacement B. Competitive exclusion
principle
C. Ecological niche ` D. Fundamental niche
E. Realized niche F. Resource partitioning
1. When two species compete for exactly the same resources (oroccupy the same niche), one is likely to be moresuccessful.One species outcompetes the other and eventually the secondspecies is eliminated
2. Some species coexist in spite of apparent competition for the sameresources. Closer study reveals that they occupy slightly different niches; dividing up the resources by pursuing slightly different resources or securing resources in slightly different ways.
3. Five species of warblers coexist in spruce trees by feeding on insects in different regions of the tree and by using differing feeding behaviors to obtain the insects
4. Niche shift
5. As a result of resource partitioning, certain characteristics may enable individuals to obtain resources in their partitions more successfully. Selection of these characteristics (or characters) reduces competition with individual in other partitions and leads to a divergence of features.6. Two species of finches that live on two different islands have similar beaks, both suited for using the same food supply (seeds). On a third island, they coexist, but due to evolution, the beak of each bird species is different. This minimizes competition by enabling each finch to feed on seeds of a different size.
7. The resources a population uses in the absence of competitors or under ideal circumstances
8. The sum total of the organismâs use of the biotic and abiotic resources in its environment
9. The resources a population actually uses
Answer and Explanation:
A. Character displacement: This refers to the change of a trait or characteristic. Two species that share the same space must develop different characteristics in order to reduce competition and make better use of resources.
5. As a result of resource partitioning, certain characteristics may enable individuals to obtain resources in their partitions more successfully. The Selection of these characteristics (or characters) reduces competition with individuals in other partitions and leads to a divergence of features.
6. Two species of finches that live on two different islands have similar beaks, both suited for using the same food supply (seeds). On a third island, they coexist, but due to evolution, the beak of each bird species is different. This minimizes competition by enabling each finch to feed on seeds of a different size.
B. Competitive exclusion principle: The competitive exclusion principle establishes that two or more species that share the same niche requirements and are in biological competition for the same resources, won´t be able to coexist indefinitely in the same space if the other ecological factors are constant. When the superior competitor occupies entirely the inferior competitor´s fundamental niche, the superior species has advantages over the other species and monopolizes all the resources. At this point, the inferior species is displaced and must adapt to use other resources changing its behavior, or must migrate to another area where it can get access to its needs, or get extinct.
1. When two species compete for exactly the same resources (or occupy the same niche), one is likely to be moresuccessful.One species outcompetes the other and eventually, the second species is eliminated
C. Ecological niche: The ecological niche is the synthesis of all the environmental factors that influence the growth, survival, and reproduction of species. These factors also include the interaction between species.
8. The sum total of the organismâs use of the biotic and abiotic resources in its environment
D. Fundamental niche: The fundamental niche refers only to physic conditions in which a species can live and survive in the absence of any interaction with other species.
7. The resources a population uses in the absence of competitors or under ideal circumstances
E. Realized niche: The realized niche refers to the restricted conditions in which a species can live and survive as a result of environment physic characteristics and the interaction with other species.
9. The resources a population actually uses
F. Resource partitioning: Resources partitioning refers to one dominant species monopolizing the resources, and the other inferior species use other resources -partially or completely-, migrates or get extinguished. A way in which species can divide resources is by living in different habitat areas. These species might eat the same food, and can roost in different places within the habitat. This resource partitioning and differentiation in the function of their physic location allows both species to coexist more effectively.

Answer:
Today, the basis for how we classify galaxies is still rooted in morphology, or how the galaxies appear. Astronomers group galaxies by shape, and although there are many different types of galaxies, most fall into one of three categories: spiral, elliptical or irregular.
Explanation:
Barred Spiral Galaxy
Barred spiral galaxies share the same features and functions as regular spiral galaxies, but they also have a bar of bright stars that lie along the center of the bulge, and extend into the disk. The bright bulge has very little activity here and contains mostly older, red stars. The bar and arms have lots of activity.including star formation.
While the classification for barred spirals is the same as it is for regular spiral galaxies, the bar must be considered as well. Short bars correlate to tighter galaxies and will be included in the designation SBa. SBb have longer bars and SBc are the longest. Most astronomers now agree that the Milky Way is a barred spiral galaxy.
Elliptical Galaxy
Elliptical galaxies can be recognized by their elongated spherical shape and their lack of nucleus or bulge at the center. Although there is no nucleus, the galaxy is still brighter in the center and becomes less bright toward the outer edges of the galaxy. Stars, gases and other materials are spread throughout the elliptical galaxy. An elliptical galaxy can be nearly round or long and cigar shaped.
It is believed that a great deal of the mass in an elliptical galaxy is due to the presence of a central black hole. These galaxies have very little activity and contain mostly old stars of low mass, because there aren’t the gasses and dust needed to form new stars.
Irregular Galaxy
Irregular galaxies are composed of gasses, dust, stars, nebulous formations, neutron stars, black holes and other elements common to all galaxies. Irregular galaxies are named so because they have no definite shape, but like all galaxies, they are in constant motion, moving outward and away from the center of our universe. Irregular galaxies are divided into two classifications: Im and IO.
Im galaxies occur most often among irregular galaxies and may show a trace of the spiral galaxy arms. IO galaxies are completely random and can be called chaotic in nature. The Magellanic clouds that border our own Milky Way Galaxy are examples of Im galaxies. Approximately 20% of our galaxies are classified as irregular
