Science

• According to him, similar species may be related by common descent. Developed the Theory of Evolution.

  Charles Darwin
• is a group of similar organisms that naturally interbreed and produce fertile offspring.

  Species
• refers to the total alleles controlling the traits of a population

  Gene pool
• Human beings have many populations that differ in physical appearance. But all humans belong to one species,

  Homo sapiens.
• A separation is caused by a geographical feature such as river, canyon, ocean, or mountain.

  Geographical isolation
• is the evolution of a new species if two subspecies would become incapable of interbreeding.

  Speciation
• any barrier that prevents successful interbreeding. Many mechanisms contribute to this barrier.

  Reproductive isolation
• when two species occupy different habitats, even in the same geographic location, they are less likely to meet and mate.

  Habitat isolation
• is a field of classifying and identifying living things.

  Taxonomy
• A _____ is composed of the different populations living in the particular habitat.

  community
• An ____ is a system that environments and their organisms form through their interactions.

  ecosystem
• the ______, the part of earth that supports life.

  biosphere
• is the relative level of a taxon or group of organisms in the hierarchy of biological classification.

  Taxonomic rank
• are classified based on a hierarchical system nomenclature.

  Organism
• is a specific group of related organisms placed at any level of classification.

  Taxon
• He established a system of category and taxon.

  Carolus Linnaeus
• Multiply asexually, like binary fission ; incapable of manufacturing their own food.

  Kingdom Monera
• All eukaryotic organisms ; animal-like protozoans and plant-like algae.

  Kingdom Protista 
• Decomposers; reproduce mainly by spores.

  Kingdom Fungi
• Divided into divisions, not phyla.

  Kingdom Plantae
• non vascular plants that reproduce by spores; grow in damp places.

  Bryophytes
• spore forming vascular plants

  Ferns
• leaves of ferns

  Fronds
• “naked seeds” (pine, fir, spruce, and cycas)

  Gymnosperms
• flowering plants; divided into 2 groups, monocot and dicot.

  Angiosperms
• biggest kingdom in terms of species diversity

  Kingdom Animalia
• jellyfishes, hydra, sea fan, corals, and sea anemone.

  Phylum Cnidaria
• Body segmentation is called metamerism

  Phylum Anelida
• Phylum Anelida - Body segmentation is called

  metamerism
• biggest animal phylum in terms of diversity and number.

  Phylum Arthropoda
• most echinoderms have a skin covered by spines and have a remarkable ability for regeneration.

  Phylum Echinodermata
• DOMAIN - A more general category; there are 3 domains, Bacteria, Archaea, and Eukarya. 
• Biodiversity, also called “Species Diversity” refers to the variety of living things on the Earth.
• Arthropods most successful animal group due to its diversity capable of adapting every type of habitat on the planet.
• World Wildlife (WWF) - “if the buying stops, the killing can too”
• Ecotourism → Responsible travel to natural areas that

  conserve the environment.
• TIES (The International Ecotourism Society)
• this path of food consumption

  Food Chain
• organism that can manufacture food from carbon dioxide and water

  Autotrophs
• Animals that feed directly on plants, like the MICE, are THE PRIMARY CONSUMERS.
