Interactions within Communities Chapter 24, Section 3
Obtaining Energy Ways to Obtain Energy Organisms can: Make their own energy Get energy by eating something else
Obtaining Energy Producers Organisms that use outside energy sources to make their own food. 2 processes: photosynthesis chemosynthesis
Obtaining Energy Producers Photosynthesis Uses sunlight to make sugars (food). Organisms contain chlorophyll.
Obtaining Energy Producers Chemosynthesis Breaks down inorganic molecules (like sulfur) for food.
Obtaining Energy Consumers Organisms that cannot make their own food. 4 types: Herbivores Carnivores Omnivores Decomposers
Obtaining Energy Consumers Herbivores Eat producers (vegetarians)
Obtaining Energy Consumers Carnivores Eat other consumers
Obtaining Energy Consumers Omnivores Eat both plants and animals
Obtaining Energy Consumers Decomposers Break down and consume wastes and decaying materials
Obtaining Energy Food Chains Simple model of feeding relationships in an ecosystem (what eats what)
Symbiotic Relationships Symbiotic Relationship A close and permanent relationships between individuals of different species. 3 types: Mutualism Commensalism Parasitism
Symbiotic Relationships Mutualism Both species benefit from the relationship.
Symbiotic Relationships Commensalism One species benefits and the other species is not harmed or helped.
Symbiotic Relationships Parasitism One species benefits but the other species is harmed.
Niches Niche How an organism survives, such as how it: Obtains food Obtains shelter Finds a mate Cares for young Avoids danger Includes any adaptations for survival.
Niches Predator-Prey Relationships Presence of a predator limits the size of prey and increases the number of species that can survive in the ecosystem.
Niches Cooperation Cooperation among organisms living in a social group. Increases the chance of survival.
Interactions Within Communities Chapter 12 Lesson 3 Notes.
Interactions Within Communities. Where does the energy in an ecosystem come from? Producers Organisms that uses an outside energy source to make energy-rich.
Science Review Section 1 Interactions Among Living Things.
Living organisms need a constant supply of energy. Obtaining Energy 3 3 Interactions Within Communities The energy that fuels most life on Earth comes.
CHAPTER TWENTY-FOUR Interactions of Life. Section 1: Living Earth The part of the Earth that supports life is the biosphere. The biosphere includes.
Interactions Within Ecosystems
Studying the Web of Life Ecology – the study of the interactions between organisms and their environment Environments have 2 parts: Biotic – living things.
Relationships in Communities Sun – source of energy that fuels most life on Earth.
Chapter 18 Interactions of Living Things The study of the interactions between organisms and their environment Click for Term.
Ecology & the Environment. Chapter 20 Ecology Study of the interactions that take place among organisms and their environment.
Interactions of Living things. Two parts of an Environment Biotic – All the living organisms in an environment. Abiotic – All the non-living objects.
Ecology Terms Review. A carnivore that feeds on the bodies of dead organisms.
Chapter 24. Section 1- Living Earth The difference in the Earth and other plants is that the Earth has an abundance of living organisms. Biosphere

Living Things Need Energy. Producers What do producers do?? How??
Interactions of Life Chapter 24. Living Earth The part of Earth that supports life is called the biosphere. – Top portion of the crust, all the waters.
Chapter 1: Interactions of Life Sections 1 & 3 Life Science.
10% Rule Only 10% of the energy present at one feeding is passed on to the next feeding level.
Objective 1.02 Identify and analyze the functions of organisms within the population of the ecosystem: Producers. Consumers. Decomposers.

Vocabulary Review Ecology. Portion of earth that supports life. Biosphere.
Unit B: Chapter 2 Vocabulary Living Things Depend on One Another.
Interactions of Living Things Chapter 1. Everything Is Connected 1.2 All living things are connected in a web of life. Ecology is the study of how.
Unit 5 Vocabulary. 1.Biosphere - The region of our planet where life resides, the combination of all ecosystems on Earth. 1.Ecosystem - A particular location.
Press F5 THESE NOTES ARE NECESSARY FOR TOMORROW’S ASSIGNMENT.
Ecosystem Notes Organism: a living thing Individual: one single organism Population: all the individuals of one kind (one species) in a specified area.
Food Chains Food Chain: a simple sequence of feeding relationships. – May include a producer, an herbivore and a carnivore. – Shows the different levels.
ECOLOGY THE STUDY OF HOW ORGANISMS INTERACT WITH EACH OTHER AND WITH THEIR PHYSICAL ENVIRONMENT.
Chapters 1 and 2 1 ZAP!
RELATIONSHIPS AMONG LIVING THINGS Day 3. Roles of living things in the environment Living things exist with other living things and with non living things.
Competition – two species share a requirement for a limited resource reduces fitness of one or both species.
Chapter 2 Biological Communities. Close, long term interactions – determine the nature of communities Habitat – where an organism lives.
12A Interpret relationships (predation, parasitism, commensalism, mutualism, competition) among organisms.
