The succession of the ecosystem

The succession of the ecosystem which point out to be the determining factor in species survival and evolution of another generation is deemed as a primary succession. Primary which refers that prior to species evolution several modifications were already initiated by nature. Successive modifications came by when species thrive in the area and during the process of survival had accidentally modified the place. Thus there are two important factors that had revived the present ecosystem into an altered ecosystem suited for the next genre of species.

Critical and Creative Thinking Questions: Answers 1. Two of the most important climate factors that determine an area’s characteristics biome are geographical location and population of species. The Earth’s rotation and revolution greatly affects climate. The population of species that thriving in the area can alter a different climatic condition such as lush vegetation can be deforested by human actions. 2. There were seven major biomes in the world. Deserts are dry places that receive less than 25 cm of precipitation each year.

The soil particle is composed of plenty of minerals such as sodium and calcium but minimal organic matter. Grasslands are windy mostly covered with dry grass and having few trees. Despite the minimal content of rain in grasslands, the soil found in this place is fertile because the biomass of decayed plants are often retain on the soil making it as a productive land. Rainforest climate condition is warm and often the soil is too thin due to greater amount of water receive. Taiga’s climate condition is cool and its soil was primarily produced from the needle leaf trees, sometimes permafrost.

Temperate forests have only two climate types, the cool season and the dry season. The soil was fertile. Similar to the taiga, tundra’s climate condition is also cool; the soil is mainly permafrost which means that water drops in the ground is unable to permeate deeper into it. It solidifies on the surface. The last biome is ocean and is the largest biome. It contains the most number of species in the world. 3. Our biome is classified under temperate rainforest. 4. There is only two of the world’s biome that is suited for agriculture.

As mentioned earlier, the grassland and the temperate forest contain most of the minerals that needed for crop growing. In the grassland, the presence of biomass makes the land to be productive and fertile; in temperate forest humus is the prevalent soil component making it an arable land for farming. 5. Aquatic organisms are widely affected by the temperature, salinity, and pH conditions of the environment. Thus to gauge the levels of these factors, you can determine what aquatic organisms will likely to thrive into it. 6. Freshwater is a body of water with low concentration of salt mostly lesser than 1%.

Freshwater types are ponds and lakes, streams and rivers and wetlands. Wetlands are regions of water were it can support aquatic plants. Estuary is where the different bodies of water meet halfway flowing into the larger body, the ocean. Flowing water based on the denotation itself, is free water that ebb on different location, standing water stagnates on a particular location. 7. Certain behavior of animals became a stimulus for change and survival. Considering that in a fight between a longer and shorter neck’s giraffe, tendency is that the longer-neck giraffe wins.

And with the gratification of copulation, since more longed-neck giraffe outrun the enemy, these actions brought about the extinction of short-necked giraffe. 8. Old-field succession pertains to a cycle of an arable land into becoming a completely forest structure land. Agriculture land being abandoned or denuded will soon be filled with tall grass; trees later on will swarm in the place returning it back into its original form. 9. Competition is the most dynamic element why new breed of species surmise. 10.

Compare the lifespan of an aquatic salamander to non-aquatic salamander. Include all physical factors such as sources of food and danger from other larger species. 11. The graph depicts on to tropical rainforest. The amount of precipitation is high and is directly in proportion to the average annual temperature. However because of the excessive amount of liquid, the soil is eroded and minerals are carried off on the erosion making the levels of soil and minerals low. 12. The picture depicts of a place near the mountain brimming with houses.

Natural calamities may occur such as earthquake triggering landslides and erosion and will endanger the homes as well as lives of the people living there. Uprooting some of those chaparrals will incur greater damage soon when heavy winter rains come. There was no roots to absorb the excess water tendency is that it may cause deluged or in winter it will cover the whole area with ice. . Resources: Succession animation.
