I will not have a computer this coming up week so I am posting my 5th scavenger hunt post now

 A heterotroph is an organism that cannot synthesize its own food and obtains its food and energy by consuming organic substances, such as other animals or plants. All animals are examples of heterotrophs including this dog.
 An ectotherm is an organism that regulates its body heat by exchanging heat with its surroundings, also known as cold-blooded. Reptiles and fish are two examples of ectotherms.
This ant is an example of an animal with a segmented body. Animals with segmented bodies are divided into three sections: the head, thorax and abdomen. 
 A keystone species is a species that has a major impact on an ecosystem. If a keystone species is removed from the habitat it will be dramatically changed. For example, elephants eat the small trees in savannas which allow the grass enough sunlight to grow. If they did not eat the trees the savannah would turn into a forest or scrublands.
A eukaryote is an organism whose cells are organized and have a distinct membrane-bound nucleus. All multi-celluar organisms are eukaryotes like this horse.
