Photosynthetic and chemosynthetic organisms can be called primary producers because they make their own food?
LenaWriter [7]

Heterotrophs are organisms that must consume food from other organisms because they are unable to synthesize their own food molecules.

<h3>What is heterotrophs?</h3>
  • An organism is referred to be a heterotroph if it is unable to manufacture food on its own and must obtain it from other sources of organic carbon, primarily plant or animal materials.
  • Heterotrophs are primary, secondary, and tertiary consumers in the food chain but not producers.
  • Because they eat producers or other consumers, heterotrophs are referred to as consumers.
  • Humans, dogs, and birds are all instances of heterotrophs.
  • In a food chain, a group of creatures that supply energy and nutrients to other organisms, heterotrophs occupy the second and third levels.
  • An organism is referred to as a heterotroph if it consumes other plants or animals for food and energy.
  • Its origins are in the Greek words hetero, which means "other," and trophe, which means "nutrition."
  • Autotrophs and heterotrophs are two main classifications of organisms depending on how they receive energy and nutrients.

Construct an explanation to predict the type of symbiotic relationship that exists between the hippo and oxpecker birds?
Allisa [31]
<h2>Answer:</h2>

<h2><em><u>The hippopotamus and the oxpecker bird are in a mutualistic and parasitic relationship. This is because the oxpecker bird gets food and protection from the hippopotamus. However, the bird gets food by making little cuts in the hippopotamus to obtain insects. This isn't entirely harmful to the hippopotamus though.</u></em></h2>
