Upright pyramid : The initial trophic level of producers in an upright pyramid exhibits a high number and biomass of organisms. Biomass decreases with each successive trophic level. Inverted pyramid: The initial trophic levels of producers in the inverted pyramid exhibit the lowest numbers and biomass of organisms. Biomass increases with each successive trophic level.
1. The atmosphere serves as the primary reservoir in the carbon cycle. 2. Fossil fuels stored in the ocean and oceanic waters act as carbon sinks in the carbon cycle.
An inverted pyramid of numbers in an ecosystem is exemplified by the dependence of numerous insects on a single tree.
The inverted pyramid of numbers is exemplified by the multitude of insects reliant on a single tree.
An inverted pyramid of numbers is exemplified by a single tree supporting numerous dependent insects.
The main characteristics of a population encompass population size, population density, natality, mortality, sex ratio, immigration, emigration, age distribution, age pyramids, expanding population, population growth forms, and biotic potential. 1) Population Density: This metric reveals the number of individuals within a population per unit space at a specific time, highlighting the spatial concentration of the … Read more
1. In any species, populations inherently face constraints on resources, fostering competition among individuals for survival and reproduction. The success in these endeavors determines the fitness of organisms. 2. Habitats possess a threshold of resource availability, allowing for the maximum sustainable population. However, growth beyond a certain limit becomes unattainable. 3. This limiting factor is … Read more
Population: A population is a collection of organisms of the same species capable of interbreeding, coexisting in a specific geographic region, and sharing or competing for comparable resources. Community: A community is formed by various populations of different species coexisting in a specific area. It results from the interaction and interdependence among diverse organisms within … Read more
Behavioral adaptions in animal Certain animals exhibit behavioral responses to cope with environmental variations. For instance, desert lizards maintain a relatively constant body temperature through adaptive behaviors. They bask in the sun to absorb heat when their temperature drops, and seek shade as ambient temperatures rise. Similarly, snakes engage in basking during winter months. These … Read more
Adaption of plants to water scarcity 1. Desert plants exhibit a thick cuticle on their leaf surfaces, providing a protective barrier to minimize water loss. 2. The stomata of these plants are sunken into deep pits, a adaptation that helps reduce water loss through transpiration. 3. Specialized in Crassulacean Acid Metabolism (CAM), desert plants utilize … Read more
