GLY 1010L Lecture Notes - Lecture 20: Symmetry In Biology, Intraspecific Competition, Interspecific Competition
Document Summary
Ecological interaction among organisms which occurs when they both need the same limited resources. Negative consequences for organisms involved interspecific competition competition in which individuals from different species compete for same resources intraspecific competition competition among organisms of the same species for the same resources methods. Plant one or more seeds than required for each species (if all germinate throw out smallest) Evenly space seeds and push them in a distance equal to about twice its minimum size major animal characteristics. Capable of motion at some point in life. Can respond quickly to external stimuli types of symmetry. Radial: can be cut all around in identical pieces. Bilateral: one axis splits the organism in half and each half looks the same. Allows muscles to grow independently from body wall types of coelom. Coelomate: animal with fluid filled cavity, in which the digestive system is supported. Acoelomate: no body cavity shared characteristics of deuterostomes and protostomes.
