Introduction In nature most organisms cannot change the nature of their environment therefore they must position themselves in an environment with favorable conditions to themselves and their offspring. This behavior is called habitat selection. Many organisms will exhibit a tactic response to these environmental factors. This tactic response can be positive or in favor of a certain environment and negative or against a certain environment.
Natural selection is the process by which evolution occurs where organisms that are better suited to the environment (‘fittest’) survive and pass on favorable traits to the offspring. Organisms must adapt to the environment in order to survive. The stickleback fish adapted to the environment by keeping/removing the pelvic structures. For example, in Frog Lake, the all of the sticklebacks had complete pelvic structures because the lake was connected to a system of streams that allowed predators into the lake. The sticklebacks in Bear Paw Lake had reduced or absent pelvic structures because little/no predators are present in the lake.
This one explanation full illustrates the importance of a balanced ecosystem and how the introduction of a predator can make sweeping changes in the
Adaptions are characteristics that living things have in response to its enviornment changing. All plants and animals have their own unique characteristics to defend and protect themselves from their enviornment around them. Organisms need to use their characteristics to find a way to reproduce, have a need for energy, protect themselves from predation, and from their own enviornment. Gray wolves have many special adaptions that help them to protect and live in their own enviornment. Gray wolves have a thick fur coat to protect themselves from their cold enviornment in the snow and their log guard hairs to keep them out of moisture.
After a breaking the record in January 2013, Lakes Michigan and Huron have gone on a record-breaking streak. Michigan and Huron, and Lake Superior, saw a surprising water level recovery from January 2013 to this November. Hydrologist Andrew Gronewold said if you to go back to the mid-1800s there have never been a faster recovery over a 23-month period, beginning in January. Lake Michigan and Huron have recovered 3.2 feet since January due to from the Detroit post in 2013. All of the Great Lakes, except Ontario, are higher this November than they were at this time last year.
Biotic components of ecosystems include plants, animals, and fungi living in that ecosystem that interact with the environment and other abiotic and biotic components. 8. Create a chart of the major characteristics of and differences between the following terrestrial biomes: Tundra, taiga, grasslands, temperate deciduous forest, desert, monsoon rainforest, tropical rainforest. 9. Create a chart of the major characteristics of and differences between the following aquatic biomes: freshwater ecosystems such as lakes, wetlands, and streams, marine biomes such as estuaries, intertidal zone, neritic zone, open sea zone, and deep sea zone.
“A child called Noah” written by Josh Greenfeld, is a story of a family with a child called Noah that is considered to be autistic. This unique story is all written in journal entries, in which the author expressed his daily challenges with his autistic son. Noah Hiro is a child born on July 1, 1966 in Westchester, New York to mother Foumi, father Josh and brother Karl. Noah seems to be okay until he stops talking at the age of two and withdraws himself from what is going on around him.
A wetland is an area where the land is saturated with water and has wetland plants. Wetlands are important because they reduce the damages of flooding. The Everglades is a very large shallow wetland in south Florida. Tens of thousands years ago, glacial retreat submerged portions of the Florida peninsula and water level rose. Today, water discharges from Orlando through the Kissimmee River and to Lake Okeechobee.
Organisms can evolve to enhance their ability to catch prey, or flee predators. Coevolution occurs in a predator-prey relationship when the prey evolves in response to pressures exerted by its predator. The predator then evolves in response to the changes in the prey (or vice versa). Inheritable adaptive traits evolve through natural selection, the process by which organisms that have developed favorable traits are capable of surviving and reproducing at greater rates, thus passing their adaptive traits to their offspring. Birds and caterpillars have a predator-prey
Movies can illustrate something beyond being fun to watch, it can teach us many educational lessons. In Finding Dory, it demonstrates many educational tools, as well as many points related to the grade 9 Science curriculum particularly in the Ecology unit. How is the film an educational tool? - Finding Dory teaches us moral lessons on the importance of family. Ex: Dory is determined to find her family throughout this entire movie when remembering small flashbacks on her adventure.
Depending on the conditions of the environment, the organisms may pass down selected traits to their offspring. These selected traits will allow for the next generation to better adapt and survive longer ["Natural Selection and Speciation - Biology."]. One example of evolution through the process of natural selection is that of the Viceroy butterfly. The Viceroy butterflies were facing extinction a little more than 100 years ago due to their inability to protect themselves or hide from their predators; mainly birds.
Biodiversity is all life on the planet. How much life is out there, however, is still quite unclear and by this time, possibly many new species may find out. Appraise of around a range from 2 million to 100 million species, with only about 1.4 million are named at this current time. The attainable diversity of uncharacterized species is very much frustrating, visualizes how many species are here and others are still missing or unrecognized. However, now days where globalization intercepts species have begun to dissolve at a very alarming and devastating rate.
These requirements for a certain life form are considered there ecological niche. To understand this more thoroughly, if we restricted a species in the forest to, a certain level of temperatures, nutrients, and pH levels then we would categorize each factor, such as the minimum temperature and a maximum temperature. We could also do the same with nutrients as well as other constraints such as water temperature or pH within food. As we can see every niche can be measured, have a range established, the space can have a set of values of how likely a species can be found. This is known as ecological phase space, which defines or means that no two species will control the same niche space, but they will compete for
The last example is ecological biodiversity, which is the variation in SC160 Basic Biology Assignment 08 the ecosystems that are found in a region or the whole planet. We see this type of biodiversity evolution all around us. For example, the forest of Maine versus the forests of Colorado. Plant and Animal
2.1 Urbanization and river water quality Due to movement of people from rural to urban areas, physical growth of the urban areas occurs, which ultimately leads to the urbanization, Over the past several years, river systems have always been extensively altered to meet various human demands, which led to them becoming the most intensively influenced ecosystems by human activities on the Earth (Nilsson, et al., 2005 )]. ‘’Among these human activities, the influence of urbanization on river systems was the most significant, and 60% of river systems were changed profoundly because of urbanization in the world’’ as cited by (Nilsson, et al., 2005 ) Recently, a number of studies have been done to understand the effects of urbanization on river water quality. The study manifested on Pearl River Delta Economic Zone is in China, that there is a positive correlation between the rapidity of urbanization and the pollution levels of urban river water.
