Transcript: by: Lauren and Sarah Population Immigration & Emigration Immigration and Emigration Immigration and Emigration are opposites. To immigrate is when individuals come into a new place from a different place. Emigration is when an individual leaves one place and goes to another. If a large number of individuals emigrate, they needs more individuals to immigrate to keep the population thriving in that specific area. These gazelles are immigrating to a new place These gazelles are immigrating to a new area Bob and friends are emigrating! They are leaving the flock. Bob Birth Rate and Death Rate Birth and Death Rate Birth and Death Rate are also opposites. Both are rates but one is about birth and the other about death. They both relate to population because if the death rate of a species is higher than the birth rate than the population will decrease. While when the birth rate is higher than the death rate the population will increase. Logistic and Exponential Population Growth and Carrying Capacity Logistic and Exponential Population Growth and Carrying Capacity Logistic Population Growth is when there's not enough resources for the population to thrive. In other words, it reaches its carrying capacity. Carrying capacity is the largest population an environment can handle. Exponential Population Growth is when a species grows greatly because of more than needed resources. Exponential and Logistic Population Growth are opposites. Graphs See carrying capacity on Logistic Growth Density-Independent Factor and Density-Dependent Factor Density-Independent and Density-Dependent factors are opposites of each other. The population size does not matter to density-independent factors. But it does matter when there are density-dependent factors. Density-Independent Factor and Density-Dependent Factor A tornado is an example of an independent factor Independent Example Disease is an example of density-dependent factor. Dependent Example

Transcript: Rain forest Ecology Poster Rubric Symbiotic Relationship Symbiotic relationship exists between ants and caterpillars. Certain caterpillar species produce sweet chemicals from "dew patches" on their backs, upon which a certain ant species will feed. Many symbiotic relationships in the rainforest are broad, across several species, such as when insects pollinate plants and get pollen or nectar as food in return and Many animals in the rain forest have a relationship showing commensalism with trees and plants throughout the forests. 1 Symbiotic relationship The food web in rain forest. The relationship food web in rain forest has producers, primary and secondary consumer . The Producers - the trees, shrubs, bromeliads and other plants. The Primary Consumers – the macaws, monkeys, agouti, tapir, butterflies, sloths, toucans. The Secondary Consumers – the jaguar and boa constrictor. Food web labels-----> 2 Food web Biomass pyramid A biomass pyramid is a diagram that compares the biomass of different trophic levels within an ecosystem. It shows the mass of producers that are needed to support primary consumers, the mass of primary consumers required to support secondary consumers, and so on. Notice that each trophic level has a smaller biomass than the one below it. 3 Biomass Pyramid Energy pyramid energy pyramid is a diagram that compares the energy used by producers, primary consumers, and other trophic levels. In other words, an energy pyramid shows how much energy is available at each trophic level. Energy is lost at each trophic level of a food chain. 4 Energy pyramid content A rainforest is an area of tall, mostly evergreen trees and a high amount of rainfall. Rainforests are Earth's oldest living ecosystems, with some surviving in their present form for at least 70 million years.which can be snake ant etc. that mostly live in rain forest. 5 Content
