Bio 110 Chapter 11 Review 1 Ecology is the study of the relationships between living organisms including humans and their physical environment it seeks to understand the vital connections between plants and animals and the world around them 2 Abiotic factors are nonliving chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems 3 List of abiotic factors Climate Disturbance Sunlight Wind e Rocks and Soils 4 Difference between weather and climate a Weather is what conditions of the atmosphere are over a short period of time b Climate is how the atmosphere quotbehavesquot over relatively long periods of time 5 Climate plays a major role in limiting species distribution because of the effects of temperature effects of water and the effect of C02 6 A disturbance is a temporary change in environmental conditions that causes a pronounced change in an ecosystem a Disturbances often act quickly and with great effect sometimes resulting in the removal of large amounts of biomass b Major ecological disturbances may include res ooding windstorms insect outbreaks trampling Earthquakes various types of volcanic eruptions tsunami and restorms 7 Fires are important because the diversity of plant and animal life dependent on the effects of re Plants cannot reproduce without re and re initiates critical natural processes by breaking down organic matter into soil nutrients 8 The distribution of terrestrial biomes are controlled by climate and disturbance 9 Biome a large naturally occurring community of ora and fauna occupying a major habitat eg forest or tundra 10 Communities change over time because when the environment changes the animals and plants living in that environment also need to change to survive 11Biological Community an interacting group of various species in a common location a For example 1 A forest of trees and undergrowth plants inhabited by animals and rooted in soil containing bacteria and fungi 12Abiotic factors vary in space and time because natural selection is random and nothing is the set Abiotic factors like climate is random 13 Biotic Factors is any living component that affects another organism including animals 9199 that consume the organism in question and the living food that the organism consumes 14 Competition is an interaction between organisms or species in which the fitness of one is lowered by the presence of another a Example In the case of cheetahs and lions since both species feed on similar prey they are negatively impacted by the presence of the other because they will have less food 15List of Biotic Factors a Competition i Predation ii Herbivory b Scavenging c Symbiosis i Mutualism ii Commensalism iii Parasitism 16 Symbiosis interaction between two different organisms living in close physical association typically to the advantage of both 17 Symbiosis Definitions a Mutualism an association between two different species where both species benefit i Example the relationship between bullhorn acacia trees and certain species of ants The acacia provides food and shelter for the ants and the ants protect the tree b Commensalism 0 An association between two different species where on species enjoys a benefit and the other is not significantly affected i Example is a whale and barnacles c Parasitism An association between two different species where the symbiont benefits and the host is harmed i Example are tapeworms eas and barnacles 18 Niche refers to the way in which an organism fits into an ecological community or ecosystem 19 Difference between a Fundamental Niche i A species includes the total range of environmental conditions that are suitable for existence without the in uence of interspecific competition or predation from other species b Realized Niche i A phrase relating to ecology defining the actual space that an organism inhabits and the resources it can access as a result of limiting pressures from other species 20 Factors that are important in limiting population size a Immigration b Emigration c Birth Rate d Death Rate 21 22 23 24 History matters for the distribution of plants and animals because of Exponential Growth and Carrying Capacity Life History Strategy a Growth b Survival c Reproduction For populations which grow exponentially growth starts out slowly enters a rapid growth phase and then levels off when the carrying capacity for that species has been reached The size of the population then uctuates slightly above or below the carrying capacity Reproductive lag time may cause the population to overshoot the carrying capacity temporarily Reproductive lag time is the time required for the birth rate to decline and the death rate to increase in response to resource limits The Connection between ecology and evolution is the day to day ecological interactions that drive evolution End of Review Reminder Next week is the Final 129 for Bio 110 The last Bio 110 Week 15 Notes will hopefully be upload by this Friday or Saturday at the latest Thank you for using Studysoup
