1. Describe what DDT is and how does it impact the food web. 2. Do you think humans health can be affected by hazardous bioaccumulates in an ecosystem? Make sure you explain using a statement from the reading. 3. Do you think DDT is the only bioaccumulate that can affect the food webs of an ecosystem?

1. DDT may alter the central nervous system of the animals living in an ecosystem contaminated with this synthetic insecticide, thereby affecting their food relationships

2. Yes, indeed it has been shown that the incidence of deaths by cancer is significantly higher in areas where DDT is used as an insecticide. Moreover, it also been shown that this compound alters the endocrine system of most animals.

3. DDT is a synthetic biomolecule insoluble in water and persistent in the environment, and it is therefore a severely hazardous formulation. Persistent organic pollutants include synthetic organochlorine pesticides (for example, DDT), industrial chemicals, especially toxic polychlorinated biphenyls such as those used in insulating fluids for transformers and capacitors and industrial hazardous substances, including polychlorinated dibenzo-p-dioxins (PCDD) and dibenzofurans (PCDF).

Explanation:

(DDT) is an organochlorine substance originally used as an insecticide, which became infamous due to its environmental impacts. In 1972, the US banned the use of DDT; however, there are countries that still use it as an insecticide for the control of mosquitoes in endemic malaria areas.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.  

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
