Which of the following would cause a decrease in the number of species in an ecosystem?
a decreasing the number of predators
b increasing the food supply
c increasing the produceſ population
d introducing a competing species

Answers

Answer 1

Answer:

d) introducing a competing species.

Explanation:

Competition refers to a dynamic partnership in which various species or populations in the environment concurrently seek to utilize the same available resources. Organisms in an ecosystem compete for the same limited nutrients and in the process, one ultimately got an edge over the other. because resources are limited in nature, the population of one species decreases at the expense of the survival of the other.

1. Write a hypothesis describing what you believe
may be causing the heavy growth of algae in the
pond. Base your hypothesis on your observations
of the two ponds.

Answers

Answer:

The hypothesis is ''the higher population of algae in a pond has a direct relation on the higher concentration of nutrients in the pond''

Explanation:

''The higher population of algae in a pond has a direct relation on the higher concentration of nutrients in the pond''. The population of algae increases vigorously when there is high concentration of nutrients such as nitrogen and phosphorus in the pond. So if there are two ponds having different concentration of nutrients so the population of algae will be higher in that pond where nutrients are present in high amount.

My hypothesis about the heavy growth of algae in the pond is "The growth of algae in the pond is caused by fertilizers and urban runoff entering the pond"

A hypothesis is a plausible explanation of some question of the real world that can be tested (either confirmed or rejected) by using the scientific method.

The scientific method is a process that involves making experiments and/or observations to compile data capable of supporting the working hypothesis.

In this case, it is possible to test my working hypothesis by measuring the concentration of nutrients (i.e., compounds rich in nitrogenous and phosphorous) associated with fertilizers and urban runoff in the pond that underwent a significant growth of algae and then statistically compare the nutrient level with those observed in ponds free of fertilizers and urban runoff.

In conclusion, a plausible explanation (i.e., a hypothesis) about the heavy growth of algae in the pond may be "The growth of algae in the pond is caused by fertilizers and urban runoff entering the pond"

these organisms obtain energy through chemosynthesis rather than photosynthesis

Answers

Answer:

Autotrophs

Explanation:

Some rare autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis. Autotrophs that perform chemosynthesis do not use energy from the sun to produce food. Instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen.

The organisms obtain energy through chemosynthesis rather than photosynthesis are called as autotrophs.

What are autotrophs ?

The autotrophs are the organisms that produce their own food material by self by using energy from sunlight or a chemical source to drive the process. Plant are the most familiar autotrophs, but there are many autotrophs are present.

An autotroph is an organism that can produce its own food material by using carbon dioxide, light, water or other chemicals. They are also called as producers.

A healthy, balanced ecosystem has _______. a. fewer producers than consumers b. more quaternary consumers than primary consumers c. more producers than consumers d. fewer primary consumers than tertiary consumers Please select the best answer from the choices provided A B C D

Answers

Answer:more producers than consumers

The ecosystem has been defined as the level of organization of the biosphere that comprises the community. A healthy, balanced ecosystem has more producers than consumers. Thus, option c is correct.

What is an ecosystem?

An ecosystem has been comprised of biotic and abiotic factors and establishes the interdependence of the living to the non-living. It comprises the ecological food pyramid and food chain that involves the flow of energy.

The producers of the food chain are the autotrophs that are more in number than the consumers as they are the primary source of the food and energy in the ecosystem.

The consumers are heterotrophs and depend on the producers for the food and energy and are lesser in number. This allows the ecosystem to be in balance as the requirements are fulfilled.

Therefore, option c. more producers than consumers are the correct blank.

Assume in otters short hair (L) is dominant to long hair (l) and black hair (B) is dominant to brown (b). If you found a black short-haired otter, you could determine its genotype by crossing it to another otter with a genotype of:

Answers

Answer:

llbb

Explanation:

The genotype of the black, short-haired otter could be determined by testing-crossing with a brown, long-haired otter whose genotype would be llbb.

Analysis of the resulting zygote from the cross would give an indication of the genotype of the otter - whether it has two dominant alleles each for the black, short-hair traits or heterozygous.

If the otter has two dominant alleles for the two traits, all the resulting zygote from the test-cross would have black, short-hair, but if it is heterozygous, a mixed phenotype set of zygote would be obtained.

Answer: The atom is mostly empty space.

Explanation:

Before to Rutherford, the accepted model for the atom was Thomson's model:

Explain why the surface of water in a container is not flat but curved?​

Answers

Answer:

it is due to high surface tension of water

Explanation:

However, for small amounts of water (like in water droplets), surface tension forces become dominant, making the water surface assume a curved, rather than flat shape. In free fall conditions (like in a spacecraft) surface tension causes even larger amounts of water to assume a spherical shape.

When the molecules of the liquid are drawn to the molecules of the container, a concave meniscus forms, which is what you generally witness. A glass tube and water cause this to happen. When molecules, like those of mercury and glass, are more attracted to one another than to the container, a convex meniscus is created.

Why is the surface of water curved?

The nature of the glass and water molecules themselves is to blame, I suppose. Polar molecules, which have positively and negatively charged ends, make up water. Due to the law of attraction between opposites, positive and negative sides of molecules are drawn to one another.
