Animals in our Ecological System and Animal Science


Ecology is simply defined as study of relationship of living things and the environment where they live.

In an ecosystem, the continued growth of plants and animals depends on maintenance of the balance between the food producers (plants) and the food consumers (animals and man). Thus,  plants and animals (included the man) are key players of an ecosystem. Figure 1.1 shows the components of an ecological system and their relationships.

Figure 1.1 The interrelationship of the components of an ecosystem.

First and foremost it is a fact  that there are two components of ecosystem and that are biotic components and abiotic components. 

 - Biotic components refer to all living things and that includes organisms found on our planet Earth. There are lots of living things on our Planet Earth and mentioned: Plants, human being, animals and there are still more.

  - Abiotic components refers to the non-living things  on Earth such as light, rocks, soil, water etc.,

Biotic and Abiotic interactions maintain the equilibrium in the environment.

Thus, animal productions are extremely under wide range of environment such as the physical and chemical conditions (climate, soil and water resources, pollution); biological condition (plant resources of food, disease and pest) and human factor (cultural condition, social structure of raisers) and involvement in the economic systems) as shown in  Figure 1.2. Thus, manager-management-animal production relationship must be taken into consideration for efficient and better productivity Figure 1.3.

# # Many environmental condition are change to fit the animals. 


- Extensive management -  less producer control over the environmental conditions in which animals are expected to produce.


# # Animals are change to fit the environment.


Right decision can be made to determine whether changing the environment or changing the adaptability of animals in the most economical way to produce optimal results of production.

Teenage Pregnancy Meaning and Conditions

Image
Teenage pregnancy - is defined as a global phenomenon in which pregnancy occured between thirteen and nineteen years of age. The most affected of this phenomenon are developing countries just like Africa, Philippines and other developing countries who are economically poor. World Health Organization says that as of 2019, adolescents aged 15–19 years in low- and middle-income countries (LMICs) had an estimated 21 million pregnancies each year, of which approximately 50% were unintended and which resulted in an estimated 12 million births (1)(2). Child marriage and child sexual abuse place girls at increased risk of pregnancy, often unintended. World Health Organization tried to call for humanitarian reason those countries affected so much with this phenomenon.

Interrelationship in the ecosystem

Image
Interrelationship in the ecosystem defined as the interaction of organism in their environment and or making disturbance to  other nearby organisms in their existence. There are four types of interaction of organism and that are mutualism, commensalism, parasitism, and competition in where:  1 . Commensialism – where one of the species lives freely while the other is unaffected of their existence. See the sample picture below: 2. Mutualism – both species benefit and enjoyed their existence and not disturbed. See the sample picture below:l 3. Parasitism – one of the species benefits while the other one is harmed and disturbed. See the sample picture below: 4. Competition – neither of the organism benefits. S ee the sample picture below: The importance of interrelationship in ecosystem are the actions of organisms made within their environment for them to survive for food, shelter, and other needs. Through their uninterrupted actions the ecosystem will function well. I
