The core threats to biodiversity are human population growth and unsustainable resource use. To date, the most significant causes of extinctions are habitat loss, introduction of exotic species, and overharvesting. Climate change is predicted to be a significant cause of extinctions in the coming century.
Here are some examples:
1. Human Activities and Loss of Habitat
2. Deforestation
3. Desertification
4. Marine Environment
5. Increasing Wildlife Trade

what organisms create energy for other organisms to consume
Answer:
Autotrophs
Explanation:
Autotrophs are organisms that use energy directly from the sun or from chemical bonds. Commonly called producers, they use the energy and simple inorganic compounds to produce organic molecules. Autotrophs are vital to all ecosystems because all organisms need organic molecules and only autotrophs can produce them from inorganic compounds. There are two basic types of autotrophs: photoautotrophs and chemoautotrophs.
Photoautotrophs
Photoautotrophs are autotrophs that use energy from sunlight to make organic compounds by photosynthesis. Photoautotrophs include plants, algae, and many bacteria, as shown in the figure below. They are the primary producers in the vast majority of ecosystems on Earth.
Chemoautotrophs
Chemoautotrophs use energy from chemical bonds to make organic compounds by chemosynthesis. Chemoautotrophs include certain bacteria and archaeans. They are the primary producers in ecosystems that form around hydrothermal vents and in hot springs.
Answer:
Autotrophs
Explanation:
Autotrophs are the only type of organism that produce energy for other organism.
However, there are different types of autotrophs that do 2 different things to produce their food.
First off, autotrophs are made up of fungi, algae, bacteria, and more commonly, plants.
They produce their own food two different ways,
The first way, and most commonly known, is photosythesis.
This is where a mix of carbon dioxide, water, and sunlight undergo 2 complex proccess to make glucose.
This is the energy that consumers, known as heterotrophs take from the autotrophs.
The second and less commonly known way of producing food is chemosythesis.
In chemosytrhesis, carbon dioxide or methane which is transformed into nutrients through the oxidization of things such as hydrogen gas and hydrogen sulfure, whihc are mainly found deep in the ocean in hydrothermal vents.
So, to answer your question:
Autrophs produce their own energy
Or more specific:
Plants, fungi, bacteria, and algae produce their own energy.

A)
The rotting remains of plants add to the fertility of the soil.
B)
The soil becomes so fertile that eel grass is replaced by other plant species.
C)
The roots from plants help stabilize the sediment, keeping it in place.
D)
The concentration of salt becomes so high that all plant life is destroyed.

tru or false?
Answer:
Tundra
Explanation:
i belive its tundra babe
True. The statement "In terms of plant life, this biome is extremely high in diversity, but there are very few animals that live here" accurately describes a tropical rainforest biome.
What is tropical rainforest biome?Tropical rainforest biome is known for its high level of plant biodiversity and relatively low number of animal species compared to other biomes. Tropical rainforests are home to a wide variety of plant species, including trees, shrubs, and epiphytes, but the dense vegetation and high rainfall make it difficult for many animal species to establish themselves.
However, the few species that are able to survive in the rainforest typically have specialized adaptations that allow them to thrive in this unique environment.

A student crosses a pure-breeding line of red-flowered poinsettias with a pure-breeding line of white-flowered poinsettias. The student observes that all the plants in the F1 generation have pink flowers. The student then crosses the F1 plants with one another and records 64 red-flowered plants, 107 pink-flowered plants and 53 white-flowered plants. What is the inheritance pattern for flower color in these poinsettias
Answer:
The correct answer is - incomplete dominance.
Explanation:
The incomplete dominance is the pattern of inheritance where the recessive allele is not completely masked by the dominant allele in the heterozygous condition and makes a mixed or blend expression of both dominant and recessive traits.
In the given question, the pattern for the flower color is incomplete dominance as in the cross between the red and white flower poinsettias produce pink instead of red in F1 generation where the condition is heterozygous. The phenotypic ratio of in F2 generation in this type of inheritance is 1:2:1 which is approximately similar in this case 64:107:53.

Answer:
Dear Seb,
Thank you for your letter, it means a lot to me seeing as though i'm still transitioning into my new school and finding friends. I miss you and all of our friends back home. it's funny, even though i have been gone for months I still refer to California as home rather than New York. It's senior year, the closing chapter of my childhood and I feel as though I have started all over again. I try to remain optimistic, but I feel like my entire life was disturbed since I moved away. I have been trying to get myself involved as much as possible for a new senior class student. An idle mind is not complacent and I find myself in a rut whenever I am not doing anything. Keeping myself busy has distracted me from my constant stress, and anxiety when I think about how far I am from everything I know and love. My current motivator is the chance that I could get accepted into a UC school and go back home. I miss you.
Love always,

In polygenic inheritance, each of the genes controlling a trait will have exactly the same influence over the trait. Group of answer choices Yes since all genes having to do with a trait always have the exact same influence on a trait. No since different genes will exert varying degrees of influence on the trait None of the other responses are satisfactory answers. No since all traits are only controlled by one gene with two alleles.
Answer:
No, since different genes will exert varying degrees of influence on the trait
Explanation:
The term quantitative heritability refers to the transmission of a phenotypic trait in which expression depends on the additive effect of a series of genes.
Polygenic heritability occurs when a trait results from the interaction of more than one gene. And these genes can also have more than two alleles. The action of many genes and alleles can cause many different combinations that are the reason for genotypic graduation.
Quantitative traits are those that can be measure, such as longitude, weight, eggs laid per female, among others. These characters do not group individuals by any precise and clear categories. Instead, they group individuals in many different categories that depend on how the genes were intercrossed and distributed during meiosis. The result depends on the magnitude in which each allele contributes to the final phenotype and genotype. When they interact, they create a gradation in phenotypes, according to the level of contribution.
Let us see, for instance, the eye color trait, which results from the interaction of many genes. Two of them significantly contribute to the color green, blue, or brown, while the rest of the involved genes play a role in defining the spectrum of phenotypes of each eye color. So, there are different tones of blue eyes, green eyes, and brown eyes, and the differences are determined by the contribution of each allele to the phenotype.
