<h2>It contains toxins</h2><h2>It killed off bird populations.</h2><h2>It caused harm to human populations.</h2>
Explanation:
Let us understand the term DDT
DDT : Dichlorodiphenyltrichloroethane
- This is a crystalline chemical compound
- Basically used for protecting insects eating crops
- It is colorless, odorless, tasteless
- Initially used as pesticides
It killed off bird populations: Though it does not kill birds directly by consuming, it has indirectly damaged the egg by making the egg's shell too thin which gets broken easily.
It controlled diseases like malaria: Since this option talks about positive attribute of DDT, this option stands invalid. This chemical compound controls mosquitoes attacking the crop.
It caused harm to human populations: DDT causes vomiting, tremors or shakiness, and seizures
It contained toxins: It contains moderate toxins.
Meta-population is the patchiness of population in space and its role is dynamic, population insatiability, coexistence of species, the maintenance of diversity.
Metapopulation is colonization and extinction dynamics. The variable of prime concern is the proportion.As the population largest approaches the environment carrying resources become more scare and growth rate slows.
The m maxima carrying number of species in environment can support indefinitely .A group of spatially separated population of similar organism which interact at some levels.It s population in which multiple populations as butterflies and cool reef fishes.Humans are evolved from multiple interconnected spread out across Africa in large meta-population.
