Day 4 Flashcards
Nematoda
Roundworms
Ocean currents
A directional movement of ocean water; surface current result from study winds over the ocean surface; deep currents result from density variations due to temperature and salinity differences
Parasitism
A relationship between two organisms of different species where one benefits and the other is harmed. a relationship between two species in which one species ,the parasite ,benefits from the other species ,the host, which is harmed
Petromyzontida
Lampreys. Jawless aquatic vertebrates with reduced vertebrae. Typically feed by attaching to a live fish and ingesting it’s blood
Photo period
Response to the changing lengths of day and night
Platyhelminthes
Called flatworms. Develop from three Germ layers, have bilateral symmetry, coelomates, thin flat body.
Population
A group of individuals that belong to the same species and live in the same area
Porifera
Sponge phylum asymmetrical organisms that lack tissues
Primary consumer
An organism that eats producers
Primates
An animal order including lemurs, tarsiers, monkeys, apes and human beings
Producer
An organism that can make its own food
Protostome
Animal with a mouth that develops from the opening in the gastrula
Radial symmetry
Body plan in which any number of imaginary plane drawn through the center of the body could divided into equal halves
Rainshadow effect
Precipitation falls on the Windward side of a mountain range, resulting in lush vegetation and a warm moist climate on one side but a desert/dryer area on the Leeward side
Range
Measure of dispersion
Realized niche
When a species occupies a smaller niche then it would in the absence of competition. Parts of a species fundamental niche that it actually uses limited by competition
Red and green algae
The closest relatives of land plants. Endosymbiosis. Photosynthetic
Relative abundance
The proportion each species represents of all individuals in the community
Reptilian
Turtles snakes lizards crocodiles alligators. First to lay eggs on land
Rotifera
microscopic rotifers, Pseudocoelom. Complete digestive tract. Filter feeders. Parsynogenesis.
SAR Clade
One of the four supergroups of eukaryotes; contains a large extremely diverse collection of Protists from three major subgroups; stramenopiles, aveolates, Rhizarians.
Secondary consumer
A member of the trophic level of an ecosystem consisting of carnivores that eat herbivores
Shannons diversity index
Study on paper
Species distribution
Plant and animal species are not distributed evenly throughout the various eco-regions of the world most of the different species of plants and animals can be found in tropical regions and more specifically in the rain forest as you move closer to the polls of the earth there is less biological diverse city
