Recycled Matter
Matter that animals need that is a waste product of photosynthesis
Oxygen
The main source of energy in an ecosystem
What is the sun
the largest ecological level
What is the biosphere
The organism living off the host
What is parasite
When both organisms benefit in the relationship
What is mutualism
The atmospheric gas that makes up 78% of Earth's atmosphere
What is nitrogen
Organisms at the base of the energy pyramid
producers or autotrophs
The largest aquatic biome (community)
What is oceans or saltwater
When organisms of the same species work together
What is cooperation
Relationship in which one organisms is harmed
What is parasitism
Matter that is given off by decayed organisms, car emissions and factories
What is carbon / carbon dioxide
Two types of general types of consumers at the third and fourth trophic levels
What are secondary and tertiary consumers
or
What are secondary and tertiary
The ecological level consisting of biotic and abiotic factors
What is ecosystem
A close living relationship between organisms from different species
What is symbiosis
The deer tick attaches to a warm-blooded animal and feeds on its blood. Ticks need blood at every stage of their life cycle. They also carry Lyme disease, an illness that can cause joint damage, heart complications, and kidney problems.
What is parasitism
Dead organisms are broken down and become a part of soil by fungi and bacteria

The ecological level that includes all the living things such as pine trees, blue jays, oak trees, and squirrels in an area
What is community
Oxpecker birds gain a safe habitat on rhinoceros’s backs and in exchange eat parasites and insects that would harm rhinos
What is mutualism
Remora fish are very bony and have a dorsal fin (the fin on the back of fish) that acts like a suction cup. Remora fish use this fin to attach themselves to whales, sharks, or rays and eat the scraps their hosts leave behind. The remora fish gets a meal, while its host gets nothing. Selfish, sure, but neither gets hurt.
What is commensalism
How nitrogen is "fixed" or changed from a gas into a compound plants and animals can use
What is by bacteria in the soil or by lightening
A trophic level has 1000 kilocalories (kcal) of energy. The next trophic level will receive this amount of energy
What is 100 kilocalories
The ecological levels from smallest to largest
What is species (individual), population, community, ecosystem, biome, biosphere
Occurs over territory, food, mates etc; can be within a species or between different species
What is competition
1. +/0
2. +/+
3. +/-

What is 1) commensalism
2) mutualism
3) parasitism
