Bell Ringer:. Define and give examples of the following: Autotroph Heterotroph Herbivore Omnivore Carnivore Decomposer. Feeding Relationships & Energy Flow. Feeding Relationships. There are 3 main types of feeding relationships 1. Producer - Consumer 2. Predator - Prey
Define and give examples of the following:
1. Producer - Consumer
2. Predator - Prey
3. Parasite - Host
Producer- all autotrophs (plants),they trap energy from the sun
Consumer- all heterotrophs: they ingest food containing the sun’s energy
animals for food.
Consumer- Carnivores- eat meat
Consumer- Omnivores -eat both plants
Nitrosomonas is a genus of bacteria and a decomposer in the coral reef.
Where would it go in our food web?
Food chain- simple model that shows how energy moves through an ecosystem in ONE direction
The ARROW shows where the ENERGY goes!
Food web- shows all possible feeding relationships in a community at each trophic level
(just 1 path of energy) (all possible energy paths)
These 3 types may be combined!
Biomass- the amount of organic matter comprising a group of organisms in a habitat.
Note: Kilogram (Kg)
is a unit of mass.
Tertiary consumers- top carnivores
Secondary consumers-small carnivores
Primary consumers- Herbivores
Joules (J) & Kilocalories (C) are units of energy
