Portfolio 2: Population Dynamics
In this portfolio, I will be exploring the different factors that influence population dynamics within ecosystems. Population dynamics refers to the ways in which populations of organisms change in size and structure over time. I will be examining the various factors that can affect population growth, such as birth rates, death rates, immigration, emigration, and competition for resources.
One key concept to consider is carrying capacity, which is the maximum number of individuals that an ecosystem can support. When a population exceeds the carrying capacity of its environment, there can be negative consequences such as scarcity of resources, increased competition, and higher death rates. I will also be looking into the role of limiting factors, which are environmental factors that can limit the growth of a population, such as food availability, predation, and disease.
Additionally, I will be exploring the concept of population growth models, such as exponential growth and logistic growth. Exponential growth occurs when a population increases at a constant rate, while logistic growth accounts for limiting factors and results in a population reaching a stable size after reaching carrying capacity.
Overall, this portfolio will delve into the intricate interactions between populations and their environments, and how these factors shape population dynamics within ecosystems.
Portfolio 3: Ecosystem Interactions
In this portfolio, I will be exploring the complex interactions that occur within ecosystems between different species and their environment. Ecosystem interactions are crucial for maintaining ecological balance and stability, as they shape the flow of energy and nutrients within the ecosystem.
One key concept to consider is the trophic levels within an ecosystem, which categorize organisms based on their position in the food chain. Producers, such as plants, are at the base of the food chain and convert sunlight into energy through photosynthesis. Herbivores consume plants, while carnivores eat other animals. Decomposers break down dead organic matter and recycle nutrients back into the ecosystem.
I will also be examining the concept of symbiotic relationships, in which two species interact with each other in a mutually beneficial or harmful way. Mutualism is a type of symbiosis where both species benefit, while parasitism involves one species benefiting at the expense of the other. Commensalism is a relationship in which one species benefits and the other is neither harmed nor benefited.
Furthermore, I will be exploring the concept of ecological succession, which is the process by which ecosystems change and develop over time. Primary succession occurs in areas with no previous vegetation, while secondary succession occurs in areas that have been disturbed but still have some soil and seeds present.
Overall, this portfolio will dive into the intricacies of ecosystem interactions and how they shape the functioning and stability of ecosystems.
