Document Summary
Concept 1. 1: events in the natural woalrd are interconnected. Connections to nature: events in natural wolrd are connect: connections when organisms interact with one another in environment. Early observations suggest that parasites cause amphibian deformaties. Laboratory experiment tests the role of parasites. Control group- h. regilla eggs not known to have frog deformation . given treatment: increase number of parasite. A field experiment suggest that multiple factors influence frog deformities. Connections in nature can lead to anticipated side effect; increase fertilizer algae growth snail eat alge, snail growth. Concept 1. 2: ecology is the scientific study of interactions between organisms and their environment. Ecology: study of interaction between organisms and environment. / study of interactions that determine distribution-geographic location and abundance of organisms. Environment science: field that incorporates natural science (ecology)/ social science( politic,economic,ethic). Public and professional ideas about ecology often differ.
