Vocabulary
An organism that can produce its own food is called a(n) __________________.
producer
What is the name of the life process that is the ability to go from one place to another at will or to react to stimuli in the environment? (Hint: It is the first life process we learned about!)
Movement
What is the main energy source for all life on earth?
The Sun
An animal that hunts for other animals is called the ______________________.
predator
What is the definition of an ecosystem?
All the living and nonliving things that interact in a given area
A(n) ____________________eats producers or other consumers.
consumer
What is the name of the life process that involves drawing in oxygen and releasing carbon dioxide (AKA breathing)?
Respiration
What are the two things that are produced as a result of photosynthesis?
oxygen and glucose
An animal that gets eaten by another animal is the _________________.
prey
True or False: A desert is an ecosystem.
True
An organism that feeds on dead producers, consumers, and wastes is called a(n) ____________________.
scavenger
What is the acronym we used to remember the names of the life processes?

What is the name of the sugar, or chemical energy, that is created when plants go through photosynthesis?
glucose
In the food chain grass - antelope - lion - vulture, which organism is the secondary consumer?
Lion
True or False: A rain forest is an ecosystem.
True
Organisms that eat plants to gain energy are known as ______________________.
herbivores
One of the life processes is sensitivity. Describe sensitivity and provide an example.
The ability to monitor an environment using the 5 senses. Example: Some species of snakes can "see" heat, so they produce a thermal image of their prey.
How is carbon dioxide involved in the process of photosynthesis?
Producers take in sunlight, water, and carbon dioxide in order to producer glucose and oxygen.
What travels through food chains/webs?
energy and matter
True or False: Air is an ecosystem.
False
Organisms that eat both plants and other animals to gain energy are known as______________________.
omnivores
Explain what a life process is and name the 7 we learned about in class.
Life processes are the body functions of living things that are necessary for survival.
Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition
Draw a model of how photosynthesis works. Label your model with the following words: energy, oxygen, carbon dioxide, water, and glucose.
(Teacher will check models)
What is one difference and one similarity between a food chain and a food web?
Difference: A food web includes multiple connected food chains while a food chain is a single linear path.
Similarity: Both show how matter and energy flow in an ecosystem. Both explain relationships between living things. Both include producers, consumers, decomposers, etc.
Name 3 types of ecosystems that we have learned about in class.
Tundra, forest, tropical rain forest, coral reef, rivers, streams, ocean, desert, etc.
