based on the living things in the pyramid, tell me what examples would fit into these categories: primary producers, primary con
algol [13]

Answer:

- Oak trees: primary producers

- Caterpillars: primary consumers

- Blue Jays: secondary consumers

- Hawks: tertiary consumers

Explanation:

A trophic pyramid, also known as ecological pyramid or energy pyramid, is a graphic representation that shows the relationships between different types of organisms (i.e., producers and consumers) at the trophic levels of an ecosystem. The primary producers are autotrophic organisms that obtain energy from sunlight and chemical compounds from nonliving sources (e.g., photosynthetic plants, algae, etc). The primary consumers are organisms that eat primary producers (e.g., herbivores), while secondary consumers are organisms that eat primary consumers (e.g., omnivores). Moreover, tertiary consumers are predators and/or omnivores that eat secondary consumers (e.g., hawks). Finally, decomposers (e.g., bacteria) are organisms that obtain nutrients and energy by breaking down dead organic material (i.e., dead organisms) at all trophic levels into nutrients.

Fill in the blanks: The original organism is called the _____________, and new organisms are called the _____________.
NARA [144]

Answer:

The original organism is called the <u><em>parent (ancestor)</em></u> , and new organisms are called the <u><em>offspring</em></u>.

Explanation:

Reproduction is one of the characteristics of life. Every living organism tends to give rise to another organism. The organism which gives rise to another organism is termed as the parent. The organism which is born is known as the offspring.

There are two basic methods of reproduction. An organism can give rise to another organism by the method of asexual or sexual reproduction.

During asexual reproduction, identical copies of the parent organism are made. During sexual reproduction, two organisms reproduce to produce non-identical offsprings.
