All the cells in a person's body have the same DNA and the same genes. However, the difference between cells in different tissues and organs is that the "expression" of the genes differs between cells. Expression means that the message from the DNA is being copied and made into protein.

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.

What is the difference between an organisms habitat and its niche?
djyliett [7]

Answer:

Organism's habitat (where a species live) can be described as all of the biotic and abiotic factors in the area where an organism lives.

Ecological niche (how species live) is composed of all of the physical, chemical, and biological factors that a species needs to survive, stay healthy, and reproduce. Niche includes food, abiotic conditions, and behavior.

Genetic diversity

Explanation:

Sexual reproductions, mutation, and crossing-over generates a wide range of genetic diversity within a population.

  • Sexual reproduction is a type of reproduction in which gametes fuses to produce a fertile and viable offspring.
  • Mutation is the process of altering genetic sequences in population to production new breeds called mutants.
  • Crossing-over is the exchange of chromosomes between two homologous pairs.

All these processes ensures that a pool of diverse gene exists within a population in order give competitive and adaptability advantage to organisms.

Explain the roles of and relationships among producers, consumers, and decomposers in the process of energy transfer in a food w
insens350 [35]

A producer is like grass, then consumers like a zebra will eat the grass, and wen the zebra dies its body breaks down and helps more grass grow. That cycle keeps going over and over, it never ends.
