A bat species (species 1) lives in a city. Another bat species (species 2) established a population in that same city after some
ddd [48]

Answer:

Roosting areas in buildings of any height are the resource partitioning of both bat species.

Explanation:

  • The <em>fundamental niche</em> refers <u>only </u>to <u>physic conditions</u> in which a species can live and survive in the absence of any interaction with other species.
  • The <em>realized niche</em> refers to the <u>restricted conditions</u> in which a species can live and survive as a result of <u>environment physic characteristics</u> and the <u>interaction</u> with other species.
  • <em>Competitive exclusion</em> refers to the <u>exclusion</u> of the inferior competitor by the superior competitor when there is not habitat differentiation, and both species can not share the same niche. In this case, the effective niche of the dominant species completely occupies the fundamental niche of the inferior competitor.
  • Resources partitioning refers to one dominant species monopolizing the resources, and the other inferior species use resources -partially or completely-, migrates or get extinguished.

A way in which species can divide resources is by living in different habitat areas. These species <em>might eat the same food</em>, and <em>can roost in different places</em> within the same habitat. This resource partitioning and differentiation in the function of their physic location allows both species to coexist more effectively.

In the present example, both bat species can coexist in the same city but the weaker bat species (species 1) roost at the top of the shorter buildings while dominant species (species 2) roost at the top of the highest buildings.

kykrilka [37]

Food chain is a step by step feeding process in an ecosystem where an organism producer is been feed on by another organism that depends on it

called consumer and it is also feed on by predator. Producer usually produce their food its includes plants, Algae, phytoplankton.

The energy level moved from the producer to the last organism on the chain.

Autotrophs are the same as producer and an Algae food chain is an example of aquatic food chain where algae serves as primary source of energy(Producer) and its been feed upon by mosquito larvea and larvea by frogs and frogs are eaten by racoon.

<h3>What is an excretory system?</h3>

An excretory system refers to a living system that is saddled with the responsibility of removing waste products from the body of a living organism, so as to prevent damage to the body and help maintain homeostasis.

Based on scientific information, the <u>urethra</u> is an organ which communicates with the lower bladder in order to enable excretion of urine from the body of a living organism.
