Answer:
To create policies to <em>control or forbid</em> the use of DDT
To create educational programs for the people.
Explanation:
As the individual can not be controlled once it is released, the actions to take abut this problem must be focused on other perspectives. Two main actions would be usefull to improve the condors´ situation:
One of them is to create policies to control or forbid the use of DDT, to reduce contamination in different food and water sources. There are too many animals that get contaminated for feeding on vegetables or other animals grown on perturbed soil, and for drinking polluted water. When these animals die, condor feeds on them and also dies. It is important to avoid using these products that affect the whole biodiversity, including human beings.
The other action is to educate people. It is very important to create educational programs that are accessible to everybody and by which it is possible to teach people about the condors´ biology, feeding behavior, and reproductive rate, among others. People should know that these animals are not dangerous, that they only feed on dead animals, and that their reproduction rate is very low. If people do not have any knowledge about this species and its situation, they will not be able to protect it.
Answer:
Evergreens are plants that maintain their leaves in all seasons and include trees such as pine, cedar, and mango. 2. Deciduous trees lose their leaves seasonally and include trees such as elm and maple. 3. Hardwoods reproduce using flowers and have broad leaves: hardwoods include trees such as maple, elm, and mango. 4. Conifer leaves are generally thin and needle-like, while seeds are contained in cones. Conifers include pine and cedar.
Explanation:
- Evergreens plants: These plants keep the foliage the year. They change leaves during their whole life, but the frequency in which they change them is not the same as the deciduous plants, and this event does not coincide with any season in particular. They do not need to lose leaves during unfavorable seasons. These species develop different strategies and adaptations to go through unfavorable weather conditions. They have special leaves to avoid water loss or freezing, some of them are thin and needle-like shaped, or might be covered with wax or fuzz. Example: Pine, cedar.
- Deciduous plants: During autumn and winter, deciduous trees from temperate forests need to store different nutrients that will be used for the plant growth during the following spring. Storaging nutrients in leaves require too much energy and constant photosynthetic activity, which might be very difficult for the plant to support during these colder seasons. To confront this situation, these species have developed some strategies such as leaves senescence. The tree stops supplying water and nutrients to the leaves, so these last ones stop producing chlorophyll. When this molecule is completely lost, other pigments that were masked by chlorophyll, show up. Before senescence occurs, pigments such as carotenoid, anthocyanin, or pheophytin reveal yellow, orange, red, purple, and brown tones, which are the characteristic autumn colors. Example: maple and elm
- Angiosperm characterize for their reproductive strategy, producing flowers and fruits, and dispersing by their seeds. These last ones are located in an ovary (in the fruit). These species attract pollinizers through the flower characteristics and reward and attract animals with their fruits, guaranteeing seeds dispersion. Example: maple and mango
- Gymnosperm does not develop flowers nor fruits. They have naked seeds on the surface of scams or leaves. Seeds frequently develop in pine cones, which are specialized branches. Example: Pine, cedar
- Conifer belongs to the Gymnosperm.
