Transcript of Science Teks 6.12 D-F

Ecosystem Organisms and Environment TEKS 6.12 (D-F) Organism: An individual living thing.
Population: All of the organisms of a specific species in an area at a certain time. All members have different genetics and capabilities.
Community: All the species in an area at a certain time. A community with high diversty is more stable than a community with low diversity becuase it is more interconnected, so it is more resisilient to disturbance.
Ecosystem: All the biotic and abiotic factors in an area. TEk 6.12 E How Do They Interact? Abiotic and biotic factors interact in many ways and need each other to survive. Biome: A large community of plants and animals that occupy a distinct region. Terrestrial biomes, typically defined by their climate and dominant vegetation, include grassland, tundra, desert, tropical rainforest, and deciduous and coniferous forests. There are two basic aquatic biomes, freshwater and marine. Tek 6.12 D Tek 6.12 E Describe biotic and abiotic parts of an ecosytem in which organisms iteract. TEK 6.12 F TEKS 6.12 (D-F) Modes of Reproduction: Asexual - By: Harshit
and Aman Organisms and Environment Identify the basic characteristics
of organisms, including prokaryotic or eukaryotic, unicellular or multicellular, autotrophic or heterotrophic, and mode of reproduction, that further classify them in the currently recognized kingdoms. Tek 6.12 F Thank You! Diagram the levels of organization within an ecosystem, including organism, population, community, and ecosystem. Multicellular- More than one cell,
eukaryotic. Eukaryotic - Nucleus, membrane
encloced organelle,
multicellular, linear DNA
larger and more complex
than prokaryotic,
circular or square in shape.
Ex: Humans Prokaryotic - TEK 6.12 D Basic Characteristics Of Organisms Classified Into Kingdoms TEK 6.12 D Tek 6.12 E Interactions
In Environment
Between Them Biotic Abiotic TEK 6.12 F Levels of Organization Within An Ecosystem Organism, Population, Community, Ecosystem Unicellular - One cell,
prokaryotic. No nucleus, no membrane enclosed organelle, unicellular, circular DNA, smaller and less complex than eukaryotic, flagelum, oval in shape. Ex: Bacteria Autotroph - An organism that can
make food itself by using
abiotic factors. Ex: plants Heterotroph - An organism that relies on other organisms for
food. Ex: animals Sexual - 1 parent, 1 set of genes (like a clone), binary fission.
Ex: plants, fungi, bacteria 2 parents, some genes from both parents. Ex: animals, humans Scientists use these characteristics and others to classify organisms into the kingdoms we know today, Biotic - A living part of an ecosystem. Abiotic - A non-living part of an ecosystem. Biotic+Biotic: An animal eating another animal. Biotic+Abiotic: Plants making food through photosynthesis, animals drinking water. Abiotic+Abiotic: Water and ice eroding land. Biome and Biosphere Biosphere: The part of the earth and its atmosphere in which living organisms exist or that is capable of supporting life. (practically everywhere) The student knows/should know all organisms are classified into Domains and Kingdoms. Organisms within these taxonomic groups share similar characteristics which allow them to interact with the living and non-living parts of their ecosystem.
