Biodiversity
The diversity/variety of plants and animals & other living things in a particular area.
Biodiversity
Means the number or abundance of different species living within a particular region.
Edward O. Wilson
Who is the father of biodiversity and quoted that “it is reckless to suppose…….”?
Taxonomy
The field of Biology that deals with classifying organisms.
Carolus Linnaeus
Who is the father of Modern Taxonomy?
Carolus Linnaeus
He is considered as the founder of the binomial system of nomenclature and the originator of modern scientific classification of plants & animals.
Binomial Nomenclature
It is identifying organisms by their genus and species’ names and is in 2 words.
Dichotomous Key
It is a series of yes/no questions that state the rules for placing items into categories.
Eubacteria, Archaebacteria, Protists, Fungi, Plants, Animal
What are the 6 kingdoms?
The Three-Domain System
The domain is more inclusive category than any other. (Bacteria, Archaea, and Eukarya)
Eubacteria
Cell walls with peptidoglycan
Archaebacteria
Cell walls do NOT contain peptidoglycan
Archaebacteria
These bacteria live in volcanic hot springs, brine pools, and black organic mud. Most survive in the absence of oxygen.
Protists
Mostly unicellular and examples are Amoeba (bottom) and Paramecium (top)
Fungi
Mostly multicellular but some unicellular and has a cell wall but does NOT make its own food.
Fungi
Mostly known as Decomposers as they change dead organic matter into usable nutrients.
Plant Kingdom
They make food by photosynthesis and most are in green as they contain chlorophyll.
Animal Kingdom
They are multi-cellular and cannot make their own food.
Vertebrates (Backbone) and Invertebrates (No Backbone)
What are the 2 groups animals can be classified into?
Body Symmetry
The arrangement of body parts
Radial Symmetry
Has body parts radiating from a central point. (Ex: Starfish and Hydra)
Bilateral Symmetry
An animal with body parts arranged in pairs on either sides of a central axis (Ex: Humans)
Asymmetry
Irregular body shape
Dorsal(Top of animal or the Back surface), Ventral(Bottom of animal or Belly), Anterior(Front of animal), and Posterior(End of animal)
What are the 4 parts of the body?
Metamorphosis
It is a series of changes during which young insects develop into adults.
Egg, Larva, Pupa, Adult
Give the process of a complete metamorphosis (Ex: Butterflies, Beetles, Flies)
Egg, Nymph(a much smaller version of the adult), Adult
Give the process of an incomplete metamorphosis (Ex: Grasshopper and cockroaches)
Biomes
Large areas(ecosystems) with the same type of climax community
Terrestrial
Biomes located on land. (Ex: Tundra, Taiga, Desert, Grassland, Deciduous Forest, and Tropical Rain Forest)
Aquatic
Biomes located in oceans, lakes, streams, or ponds. (Ex: Marine, estuary, and freshwater)
Tundra
Treeless land and only topmost layer of soil thaws during the summer. COLDEST
Bearberry
It is a common plant that can be found in the Tundra.
Taiga
Circles the North Pole and land of mine and more. Warmer and wetter than Tundra
Desert
A large, dry area and an arid region with sparse plant life and occupy about 1/5 of the Earth’s surface.
Temperate Grasslands
Large communities covered with grasses and similar small plants.
Savanna
Grassland with scattered trees and frequent fires and large mammals.
cool and dry, hot and dry, and warm and wet
What are the 3 distinct seasons in Savanna?
Chaparral
Scrubland, regions of dense shrubs along coasts.
Chaparral
Maintained by periodic fires
Temperate Deciduous Forest
A biome that has many deciduous trees which drop their leaves in the fall.
Temperate Deciduous Forest
These forests are also known as broad-leaf forests because of broad-leaved hardwood trees that loose their foliage.
Tropical Rain Forests
It is a hot humid and flourishing dense forest usually found in equator and is found near the equator.
Emergent layer, Canopy, Under story, Shrub layer, and Forest Floor
What are the layers of a tropical rain forest?
Emergent layer
Top most layer of rainforest
Canopy
It is made up the overlapping branches and leaves of rain forest
Under story
A layer made of young trees, short species tree, provide food and shelter for small animals, birds, and large predators.
Shrub layer
Dense and dark with small plants and contains shrub and ferns and other plants needing less light.
Forest Floor
Darkest of all rain forest layer making it extremely difficult for plants to grow.
Marine Biomes(salt water) and Freshwater(rivers, streams, ponds, and most lakes)
Give the 2 categories of aquatic biomes
Marine
Oceans contain the largest amount of biomass or living material of any biome on earth.
Ecologist
They study marine biomes by separating them into different zones.
Freshwater
Full of life but more so around the shoreline and in shallow areas.
Water temperature and sunlight penetration
What are the factors that limits life in freshwater biomes?
Estuary
A coastal body of water, partially surrounded by land and in which freshwater and saltwater mix.
