The Savanna A Savanna is a grassland ecosystem characterized by being sufficiently spaced so that the canopy does not close. Savannas are also characterized by seasonal water availability‚ with the majority of rainfall confined to one season. Savannas are associated with several types of biomes. Savannas are frequently in a traditional zone between forest and desert or grassland. The Savanna covers approximately 20% of the earth’s area. The Savannas is a wet and dry climate‚tropical savanna monthly

interaction between organisms forming a long term relationship with each other. Many organisms become dependent on others and they need one another or one needs the other to survive. Symbiotic interactions include forms of parasitism‚ mutualism‚ and commensalism. The first topic of discussion in symbiosis is parasitism. Parasitism is when the relationship between two animal populations becomes intimate and the individuals of one population use the other population as a source of food and can be

species. a. Parasitism i. A relationship between two species in which one species (the parasite) lives in/on another (the host) gaining food from it. ii. The parasite benefits of the cost of the host. (ex. Mosquitos) b. Commensalism i. Living on another organism without harming it. ii. One species benefits‚ the other is affected. (ex. Moss

The distribution‚ diversity and numbers of plants and animals found in ecosystems are determined by biotic and abiotic factors Students Learn to: * Compare the abiotic characteristics of aquatic and terrestrial environments The impact of abiotic characteristics on environments Abiotic Characteristic | Differences | Similarities | | Aquatic | Terrestrial | | Temperature | * Small‚ gradual changes occur | * Large variations may occur | * Temperature

What is the difference between a condition and a resource? Be able to categorize particular environmental factors as conditions OR resources (for example‚ temperature is a condition and not a resource).

Red pigment in algae for deep water illumination Relationships between living organisms: i. Commensalism a. Barnacles attach onto crabs to benefit from the movement brought by crabs and the food remains on the surface of the crabs. b. Small crabs live in oysters’ shells for protection and food by snatching food particles from the oysters

Parasitism occurs when one species feeds on another organism by living on or in the host. Mutualism occurs when two species interact in a way that benefits both. Commensalism is a species interaction that benefits one species but has little‚ if any‚ effect on the other. Ecological succession is the gradual change in species composition in an area.
