I can only have room for one species in my trailer at a time.. Sun is the principal source of energy input to biological systems. For different activities , we need energy.. The source of energy is food.. We get food from plants or animals.. But, What about plants…….?. How do populations interact?. Populations compete amongst themselves & . between . other populations. …amongst themselves. Populations compete amongst themselves & between other populations. 1. What . do ecologists call the transfer of energy that begins with the Sun and passes from one organism to the next in a food chain?. Food . transfer. Direction of energy. Energy . flow. Pyramid of numbers. TROPHIC LEVELS. An organisms trophic (feeding) level is determined by the organism’s source of energy. There are 3 main trophic levels in a food web.. Autotrophs. Heterotrophs. Saprotrophs. 1. AUTOTROPHS:. Autotroph:. Heterotroph:. Food Chain:. Food Web:. Trophic Level:. Energy is transferred in ecosystems. Producers give E to . Consumers. Food chains show flow of energy (arrows  show where energy is going). Mrs. Joelle R. King. Science Teacher. Food Chains. Food chains. use pictures or words and arrows to show the movement of energy through the trophic levels of organisms.. The . trophic level. of an organism indicates the position that the organism occupies in the food chain.. interactions. between different . organisms. and between organisms and their . environment. or surroundings.
