It is primarily concerned with the growth and regulation of population size, population genetics, demography and life history evolution, and the interactions among species.

ecological Niches: is the role and position a species has in its environment; how it meets its needs for food and shelter, how it survives, and how it reproduces.

species Interactions:within ecological webs include four main types of two-way interactions: mutualism, commensalism, competition, and predation (which includes herbivory and parasitism).

keystone Species:A keystone species is a plant or animal that plays a unique and crucial role in the way an ecosystem functions. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether

species Diversity:s the number of different speciesthat are represented in a given community (a dataset). ... Species diversity consists of three components: species richness, taxonomic or phylogenetic diversity and species evenness.
major terrestrial: is an area of land with a similar climate that includes similar communities of plants and animals. Different terrestrial biomes are usually definedin terms of their plants, such as trees, shrubs, and grasses.
  • Tundra.
  • Rainforest.
  • Savanna.
  • Taiga.
  • Temperate forest.
  • Temperate grassland.
  • Alpine.
  • Chaparral.


& aquatic biomes:Aquatic biomes are defined as the areas of ocean and other water bodies which have similar climatic condition on the Earth.
  • Ponds and lakes.
  • Streams and rivers.
  • Wetlands.
  • Oceans.
  • Coral reefs.
  • Estuaries.

Link between photosynthesis in producers and respiration in producers, consumers, and decomposers
Carbon added to the atmosphere
-tree clearing
-Burning of fossil fuels
-Warms the atmosphere
Nitrogen: Nitrogen Cycles through the biosphere, bacteria in Action (1)
-Nitrogen fixed by lightning
-Nitrogen fixed by bacteria and cyanobacteria -combine gaseous nitrogen with hydrogen to make ammonia (NH3) and ammonium ions (NH4+)
-Nitrification-Soil bacteria change ammonia and ammonium ions to nitrate ions (NO3-)
-Denitrification -Nitrate ions back to nitrogen gas

Action (2)
-Human intervention in the nitrogen cycle
-Adding NO and N2O in atmosphere from burning fossil fuels; also causes acid rain
-Destruction of forest,grasslands,and wetlands
-add excess nitrates to bodies of water
-Remove nitrogen from topsoil

phosphorus: Cycles through water, the earth's crust, and living organisms
-limit factor for plant growth
-impact of human activities -1)clearing forests
-2) removing large amounts of phosphate from the earth to make fertilizers
-3)Erosion leaches phosphate into streams

sulfur: Sulfur is found in organisms,ocean sediments , soil, rocks, and fossil fuels
-SO2 in the atmosphere
-H2SO4  and SO4
-Human activities affect the sulfur cycle
-1) burn sulfur-containing coal and oil
-2)Refine sulfur-containing petroleum
-3) Convert sulfur-contracting metallic mineral ores

water cycles: Natural renewal of water quality -3 major processes
-Evaporation
-Precipitation
-Transpiration


conservation of matter:The law of conservation of mass or principle of massconservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as system's mass cannot change, so quantity cannot be added nor removed. Hence, the quantity of mass is conserved over time.]]> 2018-11-12 17:37:13 UTC https://padlet.com/allisonbonilla22/uj8i3ywoqwrl/wish/303381387 Natural Ecosystem Change allisonbonilla22 https://padlet.com/allisonbonilla22/uj8i3ywoqwrl/wish/304406745 Climate shifts:Changing climate affects ecosystems in a variety of ways. For instance, warming may force species to migrate to higher latitudes or higher elevations where temperatures are more conducive to their survival.

species movement:
Plants, Animals, and Ecosystems. Most plants and animals live in areas with very specific climate conditions, such as temperature and rainfall patterns, that enable them to thrive. ... For example, some North American animals and plants are movingfarther north or to higher elevations to find suitable places to live.

Ecological succesion: Ecological succession is the process of change in the species structure of an ecological community over time. ... It is a phenomenon or process by which anecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat.]]> 2018-11-14 16:54:43 UTC https://padlet.com/allisonbonilla22/uj8i3ywoqwrl/wish/304406745 Ecosystem Diversity allisonbonilla22 https://padlet.com/allisonbonilla22/uj8i3ywoqwrl/wish/304407212 Biodiversity:deals with the variations inecosystems within a geographical location and its overall impact on human existence and the environment. Ecological diversity is a type of biodiversity. It is the variation in the ecosystems found in a region or the variation in ecosystems over the whole planet.

Natural Selection:is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. ... Variation exists within all populations of organisms.

Evolution:the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.

Ecosystem services:ecosystem services are the many and varied benefits that humans freely gain from the natural environment and from properly-functioning ecosystems. Such ecosystems include, for example, agroecosystems, forest ecosystems, grassland ecosystems and aquatic ecosystems.]]> 2018-11-14 16:55:18 UTC https://padlet.com/allisonbonilla22/uj8i3ywoqwrl/wish/304407212 Energy Flow allisonbonilla22 https://padlet.com/allisonbonilla22/uj8i3ywoqwrl/wish/304407475 Photosynthesis: the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

cell respiration:is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.

food webs:a system of interlocking and interdependent food chains.Food chains and food webs help us understand how eaters, the eaten, and the decomposed are interconnected in the ecosystem.
Energy glow in the food web /chain decreases at each succeeding organisms in a chain or web.


Trophic levels:each of several hierarchical levels in an ecosystem, comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy.

ecological pyramids:An ecological pyramid is a graphical representation designed to show the biomass or bio productivity at each trophic level in a given ecosystem. Biomass pyramids show how much biomass is present in the organisms at each trophic level, while productivity pyramids show the procreation or turnover in biomass.]]> 2018-11-14 16:55:37 UTC https://padlet.com/allisonbonilla22/uj8i3ywoqwrl/wish/304407475
