Food Chain Definition Biology
Abstract. In the present paper, we report the effect of nanoparticles in a three-species aquatic food chain model. It is assumed that due to the unavoidable interactions with nanoparticles, the growth rate of basal prey reduces. Fascinating dynamical scenarios in the model are explored in different bi-parametric spaces.

Loladze et al. (2000) formulated a producer-consumer Lotka-Volterra type model (LKE model) of the first two trophic levels of an aquatic food chain (algae-Daphnia) incorporating the fact that both producers and consumers are chemically heterogeneous organisms composed of two essential elements, carbon (C) and phosphorus (P). The model allows the phosphorus to carbon ratio (P:C) of the.

The NPZD model represents a simplified version of the various components of an aquatic food web. These components are nutrients (N), phytoplankton (P), zooplankton (Z), and detritus (D). The model also includes rate factors that affect the aquatic food system, listed in the sliding bars on the right side of the model.

The objective of this paper is to study the dynamical behavior of an aquatic food chain system. A mathematical model that includes nutrients and harmful phytoplankton and zooplankton is proposed and analyzed. The phytoplankton produces a toxic substance as a strategy of defense against predation by zooplankton.

marine life education Food webs describe who eats whom in an ecological community. Made of interconnected food chains, food webs help us understand how changes to ecosystems — say, removing a top predator or adding nutrients — affect many different species, both directly and indirectly. Phytoplankton and algae form the bases of aquatic food webs.

Feeding relationships within a community vary from very simple and rare food chains to highly complex and common food webs. Although most aquatic invertebrates are feeding generalists or omnivores (eating a diversity of organisms) when you consider their entire life cycles, scientists often group them into different trophic levels, such as producer, herbivore (consumer of algae or plant tissue.

the hypothesis that food chain length should increase with increasing ecosystem size (Schoener 1989, Vander Zanden et al. 1999, Post et al. 2000). Pimm and Lawton (1977) took a very different approach by examining the stability of mathematical food chain models, and found that long food chains tend to be dynamically unstable, though subsequent.
