The ecological relationships between the organisms show the interactions between the species or organisms that can negatively or positively affect them.
A frog lays thousands of eggs because many eggs die. This behavior is an example of <u>overpopulation</u>.
Overproduction can be explained as:
- Overproduction is defined as the generation of more or a high number of offspring, which can be supported by the environment.
- The high number of offspring in the environment leads to the competition of limited resources.
- Overproduction is the large number of offspring delivered to the environment, which cannot be supported by the ecosystem they are living in.
Thus, the frogs show the behavior of overproduction.

Halley's Comet is the most well-known comet. It's a "periodic" comet that comes close to Earth once in 75 years, allowing a person to see it twice in his or her lifetime. It was last seen on Earth in 1986, and it is expected to appear in the year 2061.

Although not specified, I am assuming that you want to identify the different variables and groups of this case. To answer this, the different typical factors that make up an experimental set up include: 1) dependent and 2) independent variables; 3) controlled variables; as well as the 4) control and 5) experimental group.
The dependent variable in this case is: the size of the population. While the independent variable is: the habitat space. Controlled variables in this experiment include: type and amount of food, cleanliness of the aquarium, and water temperature. The experimental group are simply the fish being observed. There are no controlled groups in this case depending on your definition. Controlled groups are usually the reference point or standard in experimental setups but this experiment wants to look at the differences of the goldfish with each other and not necessarily to a one particular goldfish and hence no controlled group.
The dependent variable is called as such because it is the one that changes depending on the factors given and is usually the one being observed. The independent variable is named as such because it remains the same throughout the experiment.

Answer:
Phylogenetic relationships
1. includes all descendants from a single common ancestor >>> monophyletic group
2. does not share any common ancestry but represents convergent evolution >>> polyphyletic group
3. includes some but not all descendants from a single common ancestor >>> paraphyletic group
Explanation:
A monophyletic taxon is a collection of organisms that have the same most recent common ancestor, thereby including an ancestor and all its descendants. Examples of monophyletic groups are angiosperms, mammals, insects, etc. A paraphyletic group is composed of some (but not all) the descendants of the most recent common ancestor. An example of a paraphyletic group includes fish and lizards. Finally, a polyphyletic taxon is composed of a group of organisms that do not contain the common ancestor of all the members of the group. An example of a polyphyletic group is composed of birds and mammals, (which constitutes a group of warm-blooded animals).
