Answer:

You drove through Iowa in the spring and noticed that along a stretch of several kilometers, every third fence post had a male red-winged blackbird perched on it defending its nesting territory. This is an example of <u>uniform dispersion.</u>

Explanation:

There are usually three dispersion patterns :

  1. Clumping
  2. Uniform dispersion
  3. Random dispersion

Clumping is the most common.

Uniform dispersion occurs when

  • resources are scarce
  • Individuals are evenly spaced in a habitat
  • Due to competition or territorial behavior

While Random dispersion occurs when resources are plentiful.

É correto afirmar que a presença de lagartas em espigas de milho se deve:
slavikrds [6]

Answer:

C - ao desenvolvimento de ovos depositados por borboletas.

Explanation:

Antes de responder a sua pergunta, eu preciso te explicar que esse não é o servidor brasileiro e sim o servidor dos EUA, você deve ter percebido que toda a linguagem do site esta em inglês. Isso significa que você só deve postar perguntas em português no campo "World Languagens" mesmo que a sua pergunta seja de biologia como essa. Caso você não faça isso, a sua pergunta pdoe ser excluída, sem ser respondida.

As lagartas que surgem nas espigas de milho, são resultado do ciclo de vida da lagarta e refere-se ao momento em que os ovos depositados nas plantas de milho pelas borboletas se chocam, liberando as lagartas, que se desenvolverão e virarão novas borboletas.

É impossivel que um grão e milho vire uma lagarta, ou que o sabubo apodrecido pode gerar lagartas. Além disso, o ´processo de geração espontanea é uma teoria cientifica invalida e que não deve ser considerada.
