Q:l Competition
Answer:
non-trophicl interactionl betweenl individualsl wherel alll speciesl arel negativelyl affectedl froml sharingl ofl limitedl resources
Q:l Interspecificl competition
Answer:
occursl betweenl membersl ofl differentl species
Q:l Intraspecificl competition
Answer:
occursl betweenl individualsl ofl thel samel species 1 / 3
Q:l Resourcesl arel featuresl requiredl for
Answer:
forl growth,l survival,l andl reproductionl andl canl bel consumedl tol thel pointl ofl depletion -Food,l water,l light,l space,l etc.
Q:l Speciesl arel additionallyl influencedl by
Answer:
temp,l pH,l salinity,l etc.l butl becausel thesel thingsl arel notl consumedl theyl aren'tl resources (Somethingl couldl bel consideredl al resourcel forl somel organismsl butl notl forl others)
Q:l Competitionl betweenl speciesl playsl keyl rolesl in
Answer:
inl evolutionl andl speciesl distribution
Q:l Exploitativel competition
Answer:
whenl individualsl reducel availabilityl ofl al resourcel whilel usingl itl (indirect) ex.l pitcherl plantsl competingl forl nutrientsl andl light
Q:l Interferencel competition
Answer:
whenl speciesl competel forl accessl tol al resourcel (direct) -food
Q:l Competitionl mayl leadl tol Antagonisticl Actionsl froml species 2 / 3
Answer:
-Interferencel inl sessilel speciesl canl includel barnaclesl crushingl eachl otherl whilel growing -Interferencel inl plantsl looksl likel individualsl growingl onl orl shadingl otherl species -ALLELOPATHYl isl whenl onel plantl speciesl releasesl toxinsl tol harml otherl species
