Predation - PowerPoint PPT Presentation


Understanding the Paradox of Plankton and Biodiversity Correlates

The paradox of plankton challenges the theory that the number of species should match available resources, as seen in diverse plankton ecosystems. Explanations include resource partitioning, temporal and spatial heterogeneity, predation, adaptation to disturbance, and evolutionary processes. Biodive

Understanding Species Interactions and Predator-Prey Dynamics

Species interactions refer to the associations between different organisms that can be positive or negative, influencing the growth and evolution of populations. Predation is a key interaction where one organism hunts and feeds on another. In predator-prey dynamics, populations fluctuate in a cyclic

Interactions Among Species in Ecosystems

Understanding species interactions in ecosystems is vital for ecological balance. It involves concepts such as carrying capacity, niche occupancy, and symbiosis. Factors affecting a population's carrying capacity include resource availability, competition, predation, parasitism, and mutualism. Diffe

Interactions between Ladybird Species in Controlling Aphid Populations

Aphids are pests that parasitize plants and can reproduce rapidly, leading to large populations. Native ladybird species may not effectively control aphid numbers, prompting the introduction of the Harlequin Ladybird. Both ladybird species now compete for food resources, with the Harlequin Ladybird
