Answer: False.

Explanation:

Thermodynamics describes the states of thermodynamic equilibrium at the macroscopic level. The states of equilibrium are studied and defined by means of extensive magnitudes such as internal energy, entropy, volume or molar composition of the system, or by means of non-extensive magnitudes derived from the previous ones such as temperature, pressure and chemical potential.

Thermodynamics deals with the processes of heat transfer, which is one of the forms of energy and how one can work with it. This area describes how matter in any of its phases (solid, liquid, gas) is transformed. So from a macroscopic point of view of matter, it studies how it reacts to changes in its volume, pressure and temperature, among other magnitudes. Thermodynamics is based on four main laws:

Thermodynamic equilibrium (or zero law)
The principle of conservation of energy (first law)
The temporary increase of entropy (second law)
The impossibility of absolute zero (third law).

In thermodynamics, a system is said to be in a state of thermodynamic equilibrium if it is incapable of spontaneously experiencing any change of state or thermodynamic process when it is subjected to certain boundary conditions (the conditions imposed by its surroundings). For this purpose, it must be simultaneously in thermal equilibrium, mechanical equilibrium and chemical equilibrium.

Entropy (symbolized as S) is a physical magnitude for a thermodynamic system in equilibrium. It measures the number of micro states compatible with the macro state of equilibrium, it can also be said that it measures the degree of organization of the system, or that it is the reason for an increase in internal energy versus an increase in temperature of the thermodynamic system.

Entropy, in an isolated system, grows in the course of a naturally occurring process. A consequence of the second law of thermodynamics is that in a state of equilibrium, entropy has a maximum value in the system that will correspond to a minimum in one of the thermodynamic potentials.

Why is the Evolution considered to be a scientific theory

Answer:

It is considered to be a scientific theory because,

Explanation:

there are many other believes or as you would call it religions that give a good explanation on how humans were created.

To be honest I don't believe the evolution because what if there was another way we were created, and not really turned into cavemen that came from monkey's or whatever.

It is honestly up to YOU on what you believe or feel about were we came from!

To my esteemed Biology colleagues: 10/15/19 I am National Park Ranger, Imani. I am writing you as my park is in desperate need o

Zanzabum

Answer:

See explanation below.

Explanation:

1. Explain the difference in the roles of producers, consumers, and decomposers in the Everglades.

In the Everglades, producers would be all species of organisms that are autotrophs such as different species of plants. Consumers are categorized into three: primary, secondary and terciary consumers. Primary consumers feed on plants (e.g. insects), secondary consumers eat the primary consumers (e.g. mice or rats), while tertiary consumers are higher predators that eat the secondary consumers (e.g. racoons). Finally, decomposers are bacteria, archaeans, fungi, or worms that live in soil which decompose organic matter.

2. Based on your knowledge of how to classify living organisms, in what domain and kingdom do the producers, consumers, and decomposers belong?

In Biology, the three domains are Archaea, Bacteria, and Eukarya; while there are six kingdoms: Archaebacteria, Eubacteria (true bacteria), Protista, Fungi, Plantae, and Animalia.

Producers, that is plants, belong to the Domain Eukarya and the Kingdom Plantae.
Primary, secondary, and tertiary consumers also belong to the Domain Eukarya and to the Kingdom Animalia as they are all animals and eukaryotes.
Decomposers are classified into the three domains: Archaea, Bacteria, and Eukarya. Bacteria belong to the domain Bacteria, archaeans belong to the domain Archaea, and worms and fungi belong to the domain Eukarya. On the other hand, decomposers are classified into Archaebacteria, Eubacteria, Protista (oomycetes), Fungi, and Animalia (worms).

3. How did energy travel in the Everglades BEFORE the alligators were removed?

Aquatic plants (producers) <-- bass <-- bluegill <-- gar <-- alligator

Aquatic plants (producers) <-- zooplankton <-- bass/bluegill <-- wood stork <-- alligator

Plants (producers) <-- cattle <-- alligator

Plants (producers) <-- insects <-- rats <-- racoons <-- alligator

4. How did removing the alligators from the food web change how energy flowed in the Everglades?

Once the alligators were removed from the food web, the populations that were once in decline began to recover because of the lack of predators. Consequently, the lack of alligators led to the uncontrollable growth of racoons, wood stork, and gar, which could also cause an alteration as they consume ecologically and economically important fish species such as the bass and bluegill.

5. How did the problem begin, and what action(s) should Ranger Imani take to solve this issue?

The problem began when the populations of alligator, an apex predator that sits at the top of the food chain, grew at an accelerated pace. This led to the uncontrolled predation of other organisms that are also fundamental to maintain an ecological balance. Therefore, Ranger Imani decided to humanely euthanize the alligators, which were preying upon them. This led to a huge increase in wood stork, gar, and racoon populations.

Alligators should not be completely removed because they help to maintain an ecological balance. Instead, Ranger Imani should work on controlling populations by implementing Wildlife Population Management strategies, such as sustainable fishing, to prevent a certain species population from reaching a high number of individuals in order to keep a healthy ecosystem where all populations are stable because removing all apex predators is not the appropriate strategy as it significantly alters the ecosystem.
